Solve for the variables in each triangle below.
Answer:
A) 41 degrees
Step-by-step explanation:
A) SohCahToa
20 = hyp.
15 = adj.
therefore, use Cos (Cah).
cos x = 15/20
x= cos^-1 (15/20)
x= 41 degrees
The required values are shown below.
What is a right angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.
Since, All the triangle are right angle triangle.
Use right angle properties,
(a)
To find the value of θ,
Use cos θ = base/hypotenuse = 15 / 20 = 3/4
cos θ = 3/4
θ = cos⁻¹ (3/4)
θ = 41.41
The value of θ is 41.41°.
(b)
Use sin θ = 3/10 =
θ = 17.45
The value of θ is 17.45.
(c)
Use Pythagorean theorem,
x² + x² = 5²
2x² = 25
x² = 25/2
x = 5/√2
(d)
sin30 = x / 8
1/2 = x/8
x = 4
cos 30 = y / 8
√3 / 2 = y/8
y = 4√3
The values of x and y are 4 and 4√3 respectively.

The diagonal of a rectangle is 10 units. The width is 6 units, What is the area of the rectangle in square
units?
Answer:
48 square units
Step-by-step explanation:
Let the length of the rectangle be x units.
By Pythagoras theorem:
[tex]x = \sqrt{ {10}^{2} - {6}^{2} } \\ x = \sqrt{ 100 - 36 } \\ x = \sqrt{64} \\ x = 8 \: units \\ [/tex]
Length of rectangle = 8 units
Area of rectangle
= Length * width

Find the prime factorization of the composite number.
795
795 =
(Type your answer using exponential notation.)
Answer:
3×5×53
Step-by-step explanation:
You can use divisibility rules to find the small prime factors.
The number ends in 5, so is divisible by 5.
795/5 = 159
The sum of digits is 1+5+9 = 15; 1+5 = 6, a number divisible by 3, so 3 is a factor.
159/3 = 53 . . . . . a prime number,* so we're done.
795 = 3×5×53
_____
* If this were not prime, it would be divisible by a prime less than its square root. √53 ≈ 7.3. We know it is not divisible by 2, 3, or 5. We also know the closest multiples of 7 are 49 and 56, so it is not divisible by 7. Hence 53 is prime.
2x-(x-(2x+3)-3x-11 help plssss
Answer:
I'll say x = 8
Step-by-step explanation:
because Simplifying
2x + -3 = 3x + -11
Reorder the terms:
-3 + 2x = 3x + -11
Reorder the terms:
-3 + 2x = -11 + 3x
Solving
-3 + 2x = -11 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3 + 2x + -3x = -11 + 3x + -3x
Combine like terms: 2x + -3x = -1x
-3 + -1x = -11 + 3x + -3x
Combine like terms: 3x + -3x = 0
-3 + -1x = -11 + 0
-3 + -1x = -11
Add '3' to each side of the equation.
-3 + 3 + -1x = -11 + 3
Combine like terms: -3 + 3 = 0
0 + -1x = -11 + 3
-1x = -11 + 3
Combine like terms: -11 + 3 = -8
-1x = -8
Divide each side by '-1'.
x = 8

a car takes 8 hours to reach to its destination with a speed of 75km/hr. how much time will it take if the speed is 60km/hr?
Answer:
10 hours
Step-by-step explanation:
speed = distance/time
s = d/t
d = st
d = 75 km/h * 8 h = 600 km
t = d/s
t = 600 km/(60 km/h) = 10 h
Answer: 10 hours

triangle town wants to build a school that is equidistant from its three cities L,M, and N. Which construction correctly finds the best location of the school? A. Construction Y because point E is the incenter of triangleLMN B. Construction Y because point E is the circumcenter of triangleLMN C. Construction X because point C is the incenter of triangleLMN D. Construction X because point C is the circumcenter of triangleLMN
Answer:
C. Construction X because point C is the incenter of triangle LMN.
Step-by-step explanation:
The construction requires that the school must be at equal distance to cities of the triangle town. Thus, it must be located at the point of intersection of the straight path from the three cities L, M, and N.
To be able to construct the school with the specification, option C is the most suitable. Construction X describe the appropriate method because point C is the incenter of triangle town of cities L, M, and N.

Answer: Answer is in the steps
Step-by-step explanation:
If we given the angle measure in variables then we will sum them up equal 180 and solve for x to determine the angle measure.
9x + x +x+4 = 180
11x + 4 = 180
-4 -4
11x = 176
x=16
In this case we can find the angle measures by using the expressions.
x = 16 degrees
x+4 = 20 degrees
9x = 144 degrees

a. there is 84.6% to 95.4% confidence that 25% of the adult citizens of the nation dreaded Valentine's Day
b. in 90% of samples of adult citizens of the nation, the proportion that dreaded Valentine's Day is between 0.196 and 0.304.
c. there is 90% confidence that the proportion of the adult citizens of the nation that dreaded Valentine's Day is between 0.196 and 0.304.
d. there is 90% confidence that 25% of the adult citizens of the nation dreaded Valentines Day.
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The sample size is [tex]n = 2500[/tex]
The sample proportion is [tex]\r p = 0.21[/tex]
The margin of error is [tex]E = 0.054[/tex]
The 90% confidence interval is mathematically represented
[tex]\r p - E < p < \r p + E[/tex]
=> [tex]0.21 - 0.054 < p < 0.21 + 0.054[/tex]
=> [tex]0.156< p < 0.264[/tex]
PLEAAASE ANSWER TIMER IS RUNNING OUT
Answer:
the correct answer is 1/2.
How i came to this answer was adding all of the number of medals together for all of the years, coming up to a total of 22. When asking about probability of any given set or amount of things, you always take the selected values and take them out of the whole amount. Years 2009 and 2012 have a whole selected value of 11 (4+7). Therefore you're "taking" 11 from 22, coming up with the fraction 11/22 seeing as that is not a answer choice the next step is to simply the fraction to 1/2.

After using a 15% off coupon, the price of a sheet cake is $30.94. What was the original price?
Answer:
The original price was 36.40
Step-by-step explanation:
p = original price of cake
using the coupon
p - 15% off = 30.94
p - .15 p = 30.94
Combine like terms
.85p = 30.94
divide each side by .85
p = 30.94/.85
p =36.40
The original price was 36.40

The ratio of adults to children on a field trip is 2:7. If there are 14 adults on the trip, how many children are there?
Answer:
49 children
Step-by-step explanation:
Adult : Child = 2 : 7
Adult = 14
2 = 14
So, 1 = 14/2 = 1 = 7 in the ratio.
So, 7 x 7 = 49 children are there.
Answer:
49
Step-by-step explanation:
Let's set up a proportion!
2 14
-- --
7 x
Now, we cross multiply
14 times 7 = 98
2 times x = 2x
98 = 2x
98 divided by 2 equals 49

if 5.49 = 70% , 100% = x so 5.49 x 100 divided 70 = X so X = 7.844 then 5.49 is the 70 % of 7.844
if 6.99 is 36% of something, 6.99 = 36%
X = 100%
so 6.99 x 100 = X (equis) x 36%
6.99 x 100 / 36 = X, so X = 19.416 . 6.99 is the 36% of 19.416

Find all values of x for which the series converges. (Enter your answer using interval notation.) [infinity] 9 x − 7 9 n n = 0 For these values of x, write the sum of the series as a function of x.
Answer:
The series converges to [tex]$ \frac{1}{1-9x} $[/tex] for [tex]$ \frac{-1}{9} < x < \frac{1}{9} $[/tex]
Step-by-step explanation:
Given the series is [tex]$ \sum_{n=0}^{\infty} 9^n x^n $[/tex]
We have to find the values of x for which the series converges.
We know,
[tex]$ \sum_{n=0}^{\infty} ar^{n-1} $[/tex] converges to (a) / (1-r) if r < 1
Otherwise the series will diverge.
Here, [tex]$ \sum_{n=0}^{\infty} 9^n x^n = \sum_{n=0}^{\infty} (9x)^{n} $[/tex] is a geometric series with |r| = | 9x |
And it converges for |9x| < 1
Hence, the given series gets converge for [tex]$ \frac{-1}{9} < x < \frac{1}{9} $[/tex]
And geometric series converges to [tex]$ \frac{a}{1-r} $[/tex]
Here, a = 1 and r = 9x
Therefore, [tex]$ \frac{a}{1-r} = \frac{1}{1-9x} $[/tex]
Hence, the given series converges to [tex]$ \frac{1}{1-9x} $[/tex] for [tex]$ \frac{-1}{9} < x < \frac{1}{9} $[/tex]
