Question

PLEASE HELP!!!

You want to find the value of x based on the information in the given image.
Which equation is NOT a correct equation to solve for the value of x?

A. x = 180/60
B. x = 3
C. 13x + 33x + 14x = 180
D. 13x + 33x + 14x = 90

Answer 1

D. 13x + 33x + 14x = 90

the angles have to add up to 180 degrees (supplementary), not 90 (complementary). all the other equations would give you the correct answer.
