If the sin 0° = 0, then which statement is true?
cos 90° = 1, because the angles are complements
cos 180° = 1, because the angles are supplements
cos 90° = 0, because the angles are complements
cos 180° = 0, because the angles are supplements

i am unable to solve this problem

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
