Textbook Problem

a) If m B C ⌢ = 69 ° , then m ∠ B O C = _____________.b) If m B C ⌢ = 64 ° , then m ∠ B A C = _______________. To determine

(a)

To find:

The measure of mBOC

Explanation

Given:

mBC=69°

Approach:

1) In a circle the measure of a central angle is equal to the measure of the arc that it intercepts.

2) In a circle the measure of an interior angle is equal to one-half of the arc that it intercepts.

Calculation:

Consider the given circle,

mBC=69°.

BC is the arc that intercept the central angle

To determine

(b)

To find:

The measure of mBAC
