Problema Solution

two angles are supplementary if the sum of their measures is 180 degrees. the measure of the first angle is 54 degrees more than three times the second angle. find the measure of the first angle.

Answer provided by our tutors

Let the second angle be x.

then,

first angle=54+3x

Given,

54+3x+x=180

or, 54+4x=180

or, 4x=180-54=126

or, x=126/4=31.5
