Answer:
130°
Step-by-step explanation:
A trapezoid's angles will add up to 360°. In this case, angle A and R have the same measure and P and Q have the same degree as well. Use this. Add 50 twice to find the measure of angles S and R together, subtract that from 360, then divide the result by two:
[tex]50+50=100\\360-100=260\\260/2=130[/tex]
The measure of angle Q is 130°
