Question

Quadrilateral ABCD is a parallelogram. If the measure of angle A is 62 degrees and the measure of angle ADB is 75 degrees, what is the measure of angle ADC, in degrees?

Answer 1

Angle ADC = 180°-60° = 120°

Explanation:

We could actually do without the additional detail pertaining to 75°. However, we could find angle CDB by difference. The solution would be 120°-75° = 45°. But this is not anymore needed by the problem because it is not asked. I guess the 75° is just a distraction.
