Question

if two angles are supplementary and one angle is 5° more than four times the other, find the angles

please answer fast its urgent

Answer 1

Hi !

Let the angles be x and y 

x + y = 180          ---> (1)

y = 4x + 5  ==> 4x - y = -5   ---> (2)

Adding equation 1 and 2 ,

x +y = 180

4x - y = -5
========

5x  = 175

x = 35

y = 180 - 35 = 145

=======================

The angles are 35° and 145°
