Question

WILL GIVE BRAINLIEST! Given that ℓ1 ∥ ℓ2 and y = 20°, find x. x = °

Answer 1

X will equal 40.

EXPLANATION: since they’re parallel and these are opposite angles, add them together to equal 180.
x+(20)+3x=180.
add common variables.
4x+20=180
subtract 29 from both sides
4x=160
divide each side by 4 so isolate x
x=40
