Let m = measure of each interior angle of a regular polygon
It turns out that
m = [180*(n-2)]/n
where n is the number of sides
We have n = 9 sides, so
m = [180*(n-2)]/n
m = [180*(9-2)]/9
m = [180*7]/9
m = 1260/9
m = 140
Each interior angle is 140 degrees
Answer: D) 140
Answer:
x = 6
Step-by-step explanation:
Similar triangles mean that it is the same shape (with same angles) but different side lengths. To find out "x", the scale factor is needed first. The scale factor is the amount that one side length is scaled (or multiplied) to equal the corresponding side length on the other similar shape.
To find the scale factor, pick a corresponding side that both triangles have a value, such as the hypotenuse, 15 and 9.
15 / 9 = 5/3 (scale factor)
The corresponding side for x is 10.
With the scale factor, divide 10 by it and x equals 6.

Answer:
18.5
Step-by-step explanation:
You have to divide. If you leave it as a fraction, you won't be able to simplify. You can check my answer by multiplying 18.5 * 2
