I finally figured out the the 2nd problem in our 2nd quiz.  Make another radius that goes to the top point.  Than you have 2 isoscles triangles.  So a bunch of congruent angles.  Than look at the now big triangle made up of the 2 smaller triangles.  Add up those angles to 180 degrees.  Substitute the congrent triangles shown earlier,  than you left with 2 angles that add to 90 degrees.  What helped me here is to draw on sketchpad.

I finally figured out the the 2nd problem in our 2nd quiz. Make another radius that goes to the top point. Than you have 2 isoscles triangles. So a bunch of congruent angles. Than look at the now big triangle made up of the 2 smaller triangles. Add up those angles to 180 degrees. Substitute the congrent triangles shown earlier, than you left with 2 angles that add to 90 degrees. What helped me here is to draw on sketchpad.
