If <RPQ is 30 degrees and <CPR is 60 degrees then how is RQ = CR?

2
  1. Assume a value for the radius, say 6 (you don’t have to but it helps)
  2. That means PR = CR = 6.
  3. Drop a perpendicular from point R to line PQ.
  4. You create two 30-60-90 triangles that should help you find RQ using PR = 6.
