First find the missing arc
- to find the missing arc you have to add the arc you know currently from 360
106 + 70 = 176
360 - 176 = 184
then divide 184/2 to get the measure of the angle
then equal them to each other
7x + 1 = 92
then solve for x
first subtract by 1 on all sides
7x = 91
then divide by 7
x= 13
