Find the value of x that makes N the Incenter of the triangle
Answer:
um im not 100% but i think 47
Step-by-step explanation:
The value of x for the given triangle is found to be 6.
What is Pythagoras theorem?Pythagoras theorem states that in a right angled triangle, the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be written as h² = p² + b².
Given triangle has N as the incentre.
Which implies that NJ = NL= NK.
Now, apply Pythagoras theorem in ΔANK to obtain,
AN² = AK²+ NK²
=> 37² = 35² + NK²
=> NK²= 37²- 35²
=> NK²= 144
=> NK = 12
Then, As per the question it can be written as,
2x = 12
=> x = 6
Hence, the value of x for the point N to be the incentre is 6.

The actual dimensions of the rectangular park are 500 cm by 600 cm and actual area of the park is 300,000 ft²
What is scale?A scale is a set of levels or numbers which are used in a particular system of measuring things or are used when comparing things.
Given that, Blake drew a scale drawing of a rectangle shaped park and used a scale of 1 cm: 20 ft
We need to find the actual width if the width on the scale drawing of the city park is 25 cm, and actual area if the width on the scale drawing of the city park is 25 cm and the length is 30 cm,
a) The given measurement of width in the drawing is 25 cm,
We have,
1 cm = 20 ft
∴ 25 cm = 20 × 25
= 500 ft
b) The given measurement of the width on the scale drawing of the city park is 25 cm and the length is 30 cm,
Actual width = 500 ft
Actual length = 20 × 30 = 600 ft
Area of rectangle = length × width
Actual area = 500 × 600
= 300,000
Hence, the actual dimensions of the rectangular park are 500 cm by 600 cm and actual area of the park is 300,000 ft²

Answer:
69°
Step-by-step explanation:
if CA and AT are congruentsides, this means that the angle of C and T must also be the same.
In order for a triangle to be a triangle, they must meet the angle of 180 degrees.
We know CAT is = to 42
So we subtract 42 from 180 = 138 degrees
we then divide 138 by 2 and we get 69
angles c + t are both 69 degrees
Answer:
69°
Step-by-step explanation:
The measure of angle A is given as 42 and the sum of interior angles in a triangle is equal to 180° we subtract 42 from 180 and divide the result with 2 because this is an Isosceles triangle since |AC| = |AT| m<C = m<T
(180 - 42) ÷ 2 = 69°

Suppose a math class contains 40 students. There are 18 females (two of whom speak Spanish) and 22 males (two of whom speak Spanish). Give all answers as decimals to at least two decimal places.
What percent of Spanish speaking students are male? Give answer as a decimal.
Answer:
50%.
Step-by-step explanation:
Given that a math class contains 40 students, and there are 18 females (two of whom speak Spanish) and 22 males (two of whom speak Spanish), in order to know the percent of Spanish speaking students that are male with respect to the total Spanish-speaking students, the following calculation has to be made:
2 + 2 = 4
2 / 4 = 0.5
Therefore, the percentage of Spanish speaking students that are male is 50%.

I If x > 0 and x^2-2x-35 = 0, then the value of x^2 is 3
Answer:
x^2 = 49
Step-by-step explanation:
Notice that the polynomial on the left of the equation can be factored out as:
x^2 - 2 x - 35 = (x - 7) (x + 5)
Then the equation: x^2 - 2 x - 35 = = 0
gives two solutions as follows:
(x - 7) (x + 5) = 0 Then either binomial factor must be zero, and therefore, x = 7 or x = -5
Since we are told that x is POSITIVE, the x = 7, and its square is 7^2 = 49.

What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Let's simplify the equation first:
10 = 2 - 4(ax - 3)
10 = 2 - 4ax + 12 (distribute the negative 4)
10 = -4ax + 14 (combine like terms)
Now we can isolate the variable x by subtracting 14 from both sides and then dividing by -4:
10 - 14 = -4ax
-4 = -4ax
x = 1/a
Therefore, the solution to the equation is x = 1/a.

Use the information given to find a convenient dass width. Then list the class boundaries that can be used to create a relative frequency histogram. (Round your class with up to the nearest multiple of 5. Use the minimum value as the smallest class boundary. Enter your class boundaries as a comma separated list.)
8 classes for 75 measurements; minimum value-20; maximum value = 175
class width
class boundaries
Answer:
a)
Class width = 19.375
b)
Class Boundaries are;
19.5 - 39.5, 39.5 - 59.5, 59.5 - 79.5, 79.5 - 99.5, 99.5 - 119.5, 119.5 - 139.5, 139.5 - 159.5, 159.5 - 179.5.
Step-by-step explanation:
Given the data in the question;
Class width = Range / Number of classes
Range = maximum - minimum = 175 - 20 = 155
Number of classes = 8
so,
Class width = 155 / 8 = 19.375
∴ the class limits will be
20 - 39
40 - 59
60 - 79
80 - 99
100 - 119
120 - 139
140 - 159
160 - 179
Low class boundary = Lower class limit - 0.5
Upper class boundary = upper class limit + 0.5
so
Class Boundaries are;
19.5 - 39.5, 39.5 - 59.5, 59.5 - 79.5, 79.5 - 99.5, 99.5 - 119.5, 119.5 - 139.5, 139.5 - 159.5, 159.5 - 179.5.
