Answer to Problem 30WE
Thus, the measure of the angle is
And, the measure of the supplement is
Explanation of Solution
Given information:
The measure of a supplement of an angle is 12 more than twice the measure of the angle.
Suppose the measure of the angle be
Then the measure of its supplement is
The measure of the supplement of the angle is 12 more than the angle implies that
Simplifying this gives
And
Thus, the measure of the angle is
And, the measure of the supplement is
