Question

An angle's measurement is 5 degrees less than 3 times the measure of its supplement. Find the measure of the angle and its supplement.

Answer 1

A supplement is 2 angles that add up to 180º. We can set this problem in an Algebraic Equation (x being the smaller angle)
x+(3x-5)=180
4x-5=180
4x=185
x=46.5
Measure of smaller angle: 46.5º Measure of supplement: 134.5º

Answer 2

Answer:

134.5
