Question

If mÐA = 3x– 2 and mÐB = 8x + 4, and the angles are complimentary, then the value of x is 9.
Select one:
True
False

Answer 1

im thinking its false ...

Answer 2

complementary angles will add up to 90 degrees.

3x - 2 + 8x + 4 = 90 -- combine like terms
11x + 2 = 90
11x = 90 - 2
11x = 88
x = 88/11
x = 8

your thinking correct.....x = 8 and not 9
