Question

Find the measure of arc CB

Answer 1

Arc CB is equals to 160

Explanation:

Add all of those numbers and subtracted by 360

Answer 2

Explanation:

Remark

Be very careful that you understand which arc you are asking for. Arc CB could be the arc made up of 53 + 79 + 68 = 200.

Somehow I get the idea that is not what you want. You want the arc that is not divided up so it is

Arc CB = 360 - Sum of the minor arcs

Arc CB = 360 -- 200

Arc CB = 160
