Question

What is mGI? I don't know what to do

Answer 1

101°

Explanation:

We are asked to find the measure of arc GI.

The measure of a circles' diameter is 360°, meaning that all of the arcs combined will equal 360°.

Add the angles of each arc:

`x + 21 + 2x - 24 + x + 43 = 360`

`4x+40=360`

Simplify:

`4x=320`

`x=80`

Substitute 80 into the value of x for Arc GI:

`80+21=101`

The measure of Arc GI is 101°.
