Answer:
10980 is the correct answer
8/10 of the students in the art class are painting.
1/2=5/10
5/10+3/10=8/10
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
