ANSWER


\begin{gathered} <1=39\degree \\ <3=51\degree \end{gathered}

Step-by-step explanation

We want to find the measures of <1 and <3 in the kite given.

The diagonals of a kite bisect each other at right angles.

This implies that:


<2=90\degree

Since the longer diagonal of the kite bisects the angle
<1=39\degreeWe can solve for <3 using the sum of angles in a triangle:


<3+39+90=180

Simplify and solve for <3:


\begin{gathered} <3=180-90-39 \\ <3=51\degree \end{gathered}

That is the answer.
