The calculated measure of the angle M is 140 degrees
How to determine the measure of the angle M
From the question, we have the following parameters that can be used in our computation:
The circle
The measure of the angle M is calculated using the theorem of angle between intersecting chords
So, we have
∠M = 1/2(120 + 160)
Evaluate the sum
∠M = 1/2 * 280
So, we have
∠M = 140
Hence, the measure of the angle M is 140 degrees
