Textbook Problem

For exercises 44 to 46, O is the inscribed circle for ∆ A B C . In exercises 45 and 46, use the result from 44.Explain why ∠ F O A         and         ∠ B O C are supplementary. To determine

To explain:

Why FOAandBOC are supplementary.

Explanation

Definition:

Supplementary Angle:

When the two angle add to 180, we say they supplement each other.

Given:

Explain FOAandBOC are supplementary.

Calculation:

By the given incircle triangle,

O is the 180 because the angle is a straight line and a straight line measures a 180
