10-35.

What is the measure of each interior angle of a regular pentagon if its total angle sum is

Once you have the measures of the pentagon, how can you use these

measures to find the measures of the angles in the isosceles triangles?

Use the Triangle Angle Sum Theorem to find the vertex angle of each star point.
