Answer 1

B 21

Answer 2

@rnick Prove it. I can easily say it's C and I'm no more right than you

Answer 3

Ok Now we know that 92+A= 180 right?

and

x+A+71=180 right?

Answer 4

Isolate the A on both equations and substitute the A to get rid of the A and solve for x

Answer 5

Okay angle A is 88 degrees due to being a line which is equal to 180. so...

180-92 = 88
then a triangle's angles add up to 180 as well so...

180-(88+71) = 21
