Two supplementry angles differ by 10x. If the acute angle is 13x, Find the obtuse angle?

Answers (1)

Given: Acute angle =13x

Let us suppose obtuse angle be y and two supplementary angles are differ by 10x.

y -10x = 13 x

y = 23x 

Sum of the supplementory angle = 23x + 13x = 180

36 x = 180

x = 5 degree

Obtuse angle y = 23(5) = 115 degree
