Example Question #51 : Geometry

The figure represents a set of supplementary angles, solve for .


12

Possible Answers:

Correct answer:

Explanation:

Supplementary angles are defined as two angles that when added together equal 

From the question, we know that the two angles are supplementary, and thus equal , so we can set up the following equation:

Next we can solve for :
