Answer:

m∠15=97°

Explanation:

In the given figure:

Angles 97° and angle 14 are corresponding angles, therefore:


m\angle14=97\degree

Next, angles 14 and 15 are vertical angles. Since the measure of vertical angles is equal, then:


\begin{gathered} m\angle15=m\operatorname{\angle}14 \\ \implies m\operatorname{\angle}15=97\degree \end{gathered}

The measure of angle 15 is 97°.
