1. △ABC is a right triangle with right angle at ∠B .

AB=34 cm
AC=55 cm

What is the measure of ∠C , to the nearest degree?

2. Which equation correctly describes the relationship between the measures of the angles and arcs formed by the intersecting secants?

m∠1=12(mAB+mCD)

m∠1=12mAB

m∠1=mAB+mCD

m∠1=12(mAB−mCD)
