Answer:
50 degrees
Step-by-step explanation:
All of the angles in the picture need to add up to 180 degrees.
<TVU = 30 degrees, so the 3 remaining angles need to add up to 150 degrees.
<QVR is = to <RVS and <RVS is = to <SVT, so all 3 angles are = to each other
<QVR = <RVS = <SVT
We have 150 degrees remaining & all 3 angles have to be the same, so each angle is 50 degrees
