The larger of two supplementary angles exceeds the smaller by 18°
Linear Equations in Two Variables (10)The larger of two supplementary angles exceeds the smaller by 18°. Find the angles.
Answer
Let larger angle be x°
Smaller angle = 180° - x°
(x) - (180 - x) = 18
2x = 180 + 18 = 198
x = 99
The two angles are 99° and 81°
