What could be the value X ??? PLEASE HELP I WILL MARK BRIANLIEST

51

Step-by-step explanation:

I mean it should add up to 180 so

180 = 63+66+x

x=51

51

Step-by-step explanation:

Since there are two angles already filled in, we should know that a straight line equals 180°, meaning that we can add the two angles we already have (which makes 129) and subtract it by 180

180

- 129

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

answer: y=0 if that is what u r looking for
