Find the measure of the arc or angle indicated. Provide a perfect solution.
Given: Arc JL = 72, Arc LK = 88
Need: Angle L
Choices:
A) 100
B) 143
C) 142
D) 137
C) 142
Solution:
We can use the formula for the measure of an angle formed by two arcs:
Angle L = (Arc JL + Arc LK) / 2
Angle L = (72 + 88) / 2
Angle L = 160 / 2
Angle L = 80
Therefore, the measure of Angle L is 80 degrees.
