TRIGONOMETRY QUESTION Can someone please explain to me on how to find out the angle using trigonometry. I also think you have to use SOH but I’m unsure. Can someone tell me how to find a)

See below.

Step-by-step explanation:

As this is a right triangle, we can use the Pythagorean theorem to find the length x.

a) the length x

b) The angle θ

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
