Problema Solution

find the measure of two supplementary angels if one of them is 18 degress less than twice the otherm

Answer provided by our tutors

the sum of supplementary angles is 180


let 'x' represent one angle, then '2x-18' represents the other angle


180 = x + 2x-18

198 = 3x

x = 66


2*66-18 = 114


the angles are 66 and 114 degrees
