In right triangle XYZ, the measure of angle Y is 30° and the measure of angle Z is 60°. Triangle XYZ is reflected across the y-axis to create triangle PQR (not shown). What is the measure, in degrees, of angle R?
Added by Travis P.
Step 1
Since angle Y is 30° and angle Z is 60°, angle X must be 90° (since the sum of angles in a triangle is 180°). Show more…
