In the right triangles shown, the measure of angle HFI is the same as the measure of angle JGH. What is the length of side GH? 

Determine the degree measure of angle A prime

RSTU is a parallelogram. If m/TUV = 78° and m/TVU = 54°, explain how you can find the measure of SRV. Show all steps of your work, and refer to any properties of triangles,
parallelograms, or triangle congruency theorems as necessary to justify your response.
