Answer:

Step-by-step explanation:

The total length of triangle is 40 in. The length of the right triangle is the total length divided by 2 which 40/2 = 20.

We have 2 right triangles. We can use the pythagorean theorem to solve for x.

a^2 + b^2 = c^2

x^2 + 20^2 = 25^2

x^2 + 400 = 625

- 400 - 400

x^2 = 225

x = 15

What is the measure of ∅? A. 2.5 π radians B. 2.5 radians C. 4 radians D. 5 radians

natka813 [3]

Answer:

C. 4 radians

Step-by-step explanation:

$20=\frac{\pi (Ctrl.Angle)(5)}{180}$

Ctrl Angle = ∅

∅ = $\frac{(20)(180)}{5\pi } =\frac{3600}{5\pi } =\frac{720}{\pi }$

in radians:

∅ = $\frac{720}{180} =4$
