Answer:
Step-by-step explanation:
The rule is if 2 chords intersect inside a circle, then the measure of the angle formed is one half the um of the measure of the arcs intercepted by the angle and its vertical angle. In other words, angle TSU = 1/2(arc TU + arc MV):
angle TSU = 1/2(90 + 80) and
angle TSU = 1/2(170) and
angle TSU = 85
