Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle. Given m AB =64° and ABC=73° , mACB=.° and mAC=.°

Inscribed angles are formed when two chords have 1 common endpoint. The measure of and  are:

Given that:

See attachment

First, we calculate using:

----- An inscribed angle is half the arc it intercepts

So, we have:

Using the same theorem, we calculate as follows:

So, we have:

Multiply both sides by 2

Hence:
