In the figure, $\angle{XYZ}$ is inscribed in circle $I$, $\angle{XYZ}=36^\circ$, $\angle{AZY}=44^\circ$, and $AB$ is tangent to circle $I$ at $Z$.  What is the measure of $\angle YIZ$, in degrees?

Draw IZ  and YI

 

Angle AZY = 44°

 

So   minor arc YZ = 2 * angle AZY = 2 (44)  =   88°

 

And central angle YIZ intercepts this arc....so  its measure = 88°
