The calculated measure of minor arc is 149°
How to determine the measure of minor arc?
From the question, we have the following parameters that can be used in our computation:
The figure
By definition
A minor arc is an arc whose measure is less than 180 degrees
Using the above as a guide, we have the following:
Minor arc = 83 + 66
Evaluate
Minor arc = 149°
Hence, the measure of minor arc is 149°
