You may or may not what this is, it's a cyclic quadrilateral.

A cyclic quadrilateral is a quadrilateral that can be inscribed in a circle where all four vertices are tangent to the circle.

Also, opposite angles of a cyclic quadrilateral *always* add up to 180 degrees.

1) We know 117 is the opposite angle, and the angles add to 180, so what is the missing? Pretty simple.

2) Same thing - 62 is the opposite angle, and the angles add to 180, so what is the missing?

You are very welcome!
