120° is an exterior angle of ∠RVU while ∠UVT is an interior angle. To get the answer 60°, you just need to subtract 120 from 180.
180-120 = 60
It is said to be that supplementary angles, which forms a linear angle together or a straight line like the line segment RVT, has a sum of 180° by adding two angles, which are ∠RVU and ∠UVT
