Angle 1 = 38 and angle 4 = 142 degrees.

Angle 1 is 38 degrees

Angle 4 is 142 degrees

Step-by-step explanation:

the square root of what number? if you add that, then someone will probably answer the question.

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
