Given: m ∠ 1=72 ° , m D C ⌢ = 34 ° Find: a) m A B ⌢ b) m ∠ 2 To determine

(a)

To find:

mAB when m1=72° and mDC=34°.

Explanation

Theorem:

The measure of an angle formed by two chords that intersect that intersect within a circle is one-half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

Calculation:

mAB when m1=72° and mDC=34°.

By Theorem,

m1=12(mAB+mDC)7

To determine

(b)

To find:

m2 when m1=72° and mDC=34°.
