Question

In quadrilateral ABCD, MZA = 72, mZB = 94, and m2C = 113. What is m2D?

Answer 1

First, let's picture the problem

Let's label the angle D as x

Remember that the sum of angles in a quadrilateral is 360

`\begin{gathered} 72^0+94^0+113^0+x=360^(\square) \\ x=81^0 \\ m\angle D=81^0 \end{gathered}`
