Answer 2

Answer:

$\frac{1}{2}$ x = 80

(x -15) =  145

(x - 25) =  135

Step-by-step explanation:

Add all the angles and equal them to 540

$\frac{1}{2}$ x + $\frac{1}{2}$ x + (x -15) + 100 + (x - 25) = 540

add x's and numbers together

x + x - 15 + 100 + x - 25 = 540

3x + 60 = 540

3x = 480

x = 160,

substitute into angles

$\frac{1}{2}$ x = $\frac{1}{2}$ (160) = 80

$\frac{1}{2}$ x = $\frac{1}{2}$ (160) = 80

(x -15) = 160 - 15 = 145

100

(x - 25) = (160 - 25) = 135

adding all angles equal to 540
