Find two supplementary angles if one angle is three times larger than the other angle.

Sagot :

First angle: x
Angle's supplement: 3x
Sum of the measures of the supplementary angles:  180°

Equation:
x + 3x = 180°
4x = 180°

4x/4 = 180°/4
x = 45°

First angle: x = 45°
Supplementary angle135°

The supplementary angles have measurements of 45° and 135°.
