Question

angle s = 30 ° arc rs = 84 degrees, and is tangent to the circle at R. Find angle U.
The figure is not drawn to scale.

Answer 1

can you post the figure ?

Answer 2

here is the figure

Answer 3

angle U is 1/2 the difference in the intercepted arcs
in other words 1/2 of (arc RS - arc RT)

Answer 4

they tell you arc RS. Can you figure out the length of arc RT ? (use the idea that angle S is 1/2 of its intercepted arc)
