Answer:
one angle is 40 and other is 140
Explanation:
Let one angle be x and other be y where x is smaller than y
we know that x + y =180 (equation 1)
and 3x +20 = y (equation 2)
so applying the value of equation 2 in equation 1 we get
x + 3x +20 = 180
4x + 20 = 180
4x = 160
x = 40
please rate the answer
Answer:
Two angles are supplementary. If one angle is x, then other angle is (180-x)
let x > (180-x)
x = 3(180-x)+20 = 560 - 3x
hence 4x = 560 or x = 140
hence angles are 140° and 40°
