1: in ABC, m∠A measures twice m∠B. if exterior angle at C measures 126°, find m∠A. 2: in abc the measure of the exterior angle at b 100° if m∠A is 4 times larger than m∠C find m∠C.

PLEAS I NEED THAT FOR TODAY PLEAS

you probably already have the answer but anyways it's b. 15.0

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
