Can someone help me out with this problem

x = 117°

Step-by-step explanation:

Vertically opposite angles are equal

One of the triangle's properties is that the exterior angle is the sum of the opposite angles (interior angles)

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
