Question

Instructions: Find the measure of the angle indicated.Correction: 225° is 250°

Answer 1

Given the following theorem:

$\begin{gathered} a+b=360\degree \\ x=\frac{a-b}{2} \end{gathered}$

Now, from the problem, we identify:

$\begin{gathered} m\angle JKL=x \\ a=250\degree \\ b=360\degree-250\degree=110\degree \end{gathered}$

Finally, using the theorem:

$\begin{gathered} x=\frac{250\degree-110\degree}{2} \\ \\ \therefore m\angle JKL=70\degree \end{gathered}$
