Chapter 11.1, Problem 40STP

To determine

To find:Which angles are not supplementary

Answer to Problem 40STP

Option G is correct.

Explanation of Solution

In order for angles to be supplementary, the sum of their measures must be ${180}^0$ .

The sum of of their measures of the angles in options F,H and J are ${180}^0$

The sum of measures of the angles in Option G,

  $\angle EZC$ and $\angle CZD$ is not ${180}^0$

So,

Option G is correct.
