Question

Two supplementary angles are such that one is two third of the other. Find them.

Answer 1

Step-by-step explanation:

let one angle be x

then the the other angle is (2/3)x

since the angles are supplementary angles

$x+2x/3=180\\5x/3=180\\5x=540\\x=108$

$2x/3=2*108/3\\=72$

therefore the angles are 108 and 72
