Question

if an angle is thrice its supplymentry angle , find the measures of the angles

Answer 1

Let suplementary angle be 'x'
So the angle will be 3x
x +3x=180
4x=180
X=45
Angle is 3x= 3*45 =125

Answer 2

Let the angle be x.

Given x + 3x = 180

4x = 180

x = 45.

Then 3 *x = 135.

The measures of angles are 45 and 135.
