Question

K & m are supplementary angles . If m < K=3x+8 and m 12 years ago

Answer 1

supplementary angles add up to 180 degrees
so set them equal to 180...

3x + 8 + x + 12 = 180 -- combine like terms
4x + 20 = 180 -- subtract 20
4x = 160 -- divide by 4
x = 160/4
x = 40

m < K = 3x + 8
3(40) + 8
120 + 8
128

m < M = x + 12
40 + 12
52

check..
128 + 52 = 180
180 = 180 (correct)

< K = 128 and < M = 52
