Answer:
Step-by-step explanation:
As we can see, this triangle has 2 equal sides in length, which makes it an isosceles triangle. As the Base Angles Theorem states, the base angles of an isosceles triangle are congruent. In this case, angles a and b are the base angles. We now know they are both congruent, so we'll mark them both as a. Next, we notice that the measure of the other angle is 122°. We also know that the sum of all of the angle measures in a triangle is 180°. Using algebra and what we know so far, we can write this equation:
122°+a+a=180°.
When we solve for a, we get:
122°+2a=180° (add a and a)
2a=58° (subtract 122 from both sides)
a=29°
Since we know a=b, b=29°.

Please Help me
Answer ASAP AND correctly
======================================================
Explanation:
Angle A' is given to be 59 degrees. Due to the symmetry of the reflection, this is also the measure of angle A as well. Angle B is shown to be 67 degrees.
Angles A,B,C add to 180 degrees. This is true for any three angles of a triangle.
A+B+C = 180
59+67+C = 180
126+C = 180
C+126 = 180
C+126-126 = 180-126 ... subtract 126 from both sides
C = 54

4x2 – 1 = 15
find the justification
Answer:
see below
Step-by-step explanation:
4x^2 – 1 = 15
Add 1 to each side using the addition property of equality
4x^2 -1+1 =15+1
4x^2 =16
Divide each side by 4 using the division property of equality
4x^2/4 =16/4
x^2 = 4
Take the square root of each side
sqrt(x^2)= ±sqrt(4) property of square roots
x = ±2

At a school fair, students were challenged to hit one of the small congruent circles on the large rectangular board with a ball. Find the probability of hitting any small circle. Type answer as a percent.
Answer:
4.66%
Step-by-step explanation:
The probability of hitting any small circle is the combined are of the three circles divided by the area of the rectangle.
p(circle) = (combined are of the the circles)/(area of rectangle)
area of circle = (pi)r^2
area of rectangle = length * width
p(circle) = [3 * (pi)r^2]/(length * width)
p(circle) = [3 * (3.14159)(3^2)]/(52 * 35)
p(circle) = [27(3.14159)]/(1820)
p(circle) = 0.0466 = 4.66%

Miguel finished his English assignment in 1/3 hours. Then he completed his history assignment in
3/5 hours. What was the total amount of time Miguel spent doing these two assignments?
Write your answer as a fraction in simplest form.
Answer:
14/15
Step-by-step explanation:
Th total amount of time Miguel spent doing the two assignments is 14/15 hours.
To find the total amount of time Miguel spent doing the two assignments, to add the time it took for each assignment.
Miguel spent 1/3 hours on his English assignment and 3/5 hours on his history assignment.
To add these fractions, to have a common denominator. The least common multiple (LCM) of 3 and 5 is 15.
Converting the fractions to have a denominator of 15:
1/3 = 5/15 (multiply numerator and denominator by 5)
3/5 = 9/15 (multiply numerator and denominator by 3)
Now add the fractions:
5/15 + 9/15 = 14/15

The proportional statements that are true for finding the value of x in the enlargement of the triangle are:
6/x = 9/16
9/x = 6/16
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
We can use the property of similar triangles to set up these proportional statements.
Since the two triangles are similar, their corresponding sides are in proportion to each other.
We can set up the proportion:
smaller side length / larger side length = corresponding smaller side length / corresponding larger side length
Substituting the given side lengths, we get:
6 / 16 = 9 / x
Now,
Solve for x, we can cross-multiply and simplify:
6x = 9 x 16
x = 24
Substituting x = 24 into the other proportional statement.
9 / 24 = 6 / 16
Cross-multiplying and simplifying.
144 = 144
which is true.
And,
The other proportional statements are not true for finding the value of x.
Thus,
The proportional statements that are true for finding the value of x in the enlargement of the triangle are:
6/x = 9/16
9/x = 6/16

The number of bags of candy that Shelly ordered is 16.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
Given hat,
Total amount that Shelly paid = $15
Shipping flat rate = $3
Total amount for the bags = 15 - 3 = $12
Cost of each bag = $0.75
Number of bags bought = 12 / 0.75 = 16
Hence the total number of bags is 16.

Apply the formula of each shape to determine the
volumes
What is the exact volume of the composite figure?
V=
л cm3
V (cone) = (1÷3) × (r×r×h) л cm3
3 cone = 1 cylinder (if "h" and "r" is same)
There is two cone...
1st one: (1÷3) × 3×3×5 л cm3 = 15л cm3
2nd one: (1÷3) × 3×3×8 л cm3 = 24л cm3
15 + 24 = 39л cm3
The exact volume of the composite figure is,
⇒ 122.46 cm³
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Radius of cone = 3 cm
Upper height of cone = 5 cm
Lower height of cone = 8 cm
Now, We get;
Volume of cone = πr²h / 3
Hence, For upper cone is,
⇒ V = 3.14 × 3² × 5 / 3
⇒ V = 47.1 cm³
For lower cone is,
⇒ V = 3.14 × 3² × 8 / 3
⇒ V = 75.36 cm³
Thus, The exact volume of the composite figure is,
⇒ 47.1 + 75.36
⇒ 122.46 cm³

John's parents purchased their first home in the 1980s with a 30-year
mortgage at 17.5%. Their home was purchased for $125,000. What was their
monthly mortgage payment?
A. $1832.91
B. $1872.90
C. $1965.72
D. $1765.92
Answer:
Option A,$ 1,832.91 is correct
Step-by-step explanation:
The monthly payment can be computed using the below pmt formula i excel shown below:
=pmt(rate,nper,-pv,fv)
rate is the monthly rate on the mortgage which is 17.5%/12=0.014583333
nper is the number of months of payment i.e 30*12=360
pv is the amount of the loan which is $125,000
fv is the total amount of repayment which is unknown
=pmt(0.014583333 ,360,-125000,0)=$ 1,832.91
The correct option is A,$ 1,832.91 which is the amount of money they need to pay back on the mortgage for 360 months
