1. What is the measure of the angle ABC, if arc ADC is equal to 160 and arc EF is equal to 80?
✓ Suppose arc ADC is x and arc EF is y. We will use the formula, (x-y)/2.
✓ Angle ADC is equal to half of the difference between two given arcs.
2. What is the measure of the angle MQL, if arc MKL is equal to 220 and arc ML 140 is equal to 80?
✓ Suppose arc MKL is x and arc ML is y. We will use the formula, (x-y)/2.
✓ Angle MQL is equal to half of the difference between two given arcs.
