Question

PLSSSSS HELP!!!!!!!!!

Answer 1

x=30º

∠CAB=60°

∠ACB=80°

Explanation:

Because the angles of every triangle add up to 180º, we know that:

`2x+20+2x=180-40\\ 4x=180-40-20\\ 4x=180-60\\ 4x=120\\ x=(120)/(4)`

x=30º

Plug that in for x on both angles, and you will get

∠CAB=60°

∠ACB=80°
