1) Given: m
EY (arc) =2mYI(arc
Prove: m∠K+m∠EXY= 5/2m YI (arc)
2) *Prove: If two circles are tangent internally and the center of the larger circle lies on the smaller circle, then any chord of the larger circle drawn from the point of tangency is bisected by the smaller circle.

Statement Reason Please (PS if you go to Russian math these are in the HW)
