Question 688156
Two angles are supplementary. One angle is 4 degrees less than three times the other. Find the measurement of the angles.
==============
Call the angles A & B
A + B = 180 degs
A = 3B - 4
-----
Solve for A & B
Sub for A in the 1st eqn
(3B-4) + B = 180
4B = 184
B = 46 degs
---
A = 180 - B
A = 134 degs
