quadrialteral abcd is aparallelogram.If the measure of angle A is 62 degrees, measure of ADB is 75 degrees, what is the measure of angle ADC in degrees

2 answers

assuming the vertices are labeled in order, DB is a diagonal.

Since angle ADC is just angle D, and since consecutive angles of a parallelogram are supplementary, then angle A & angle D add to 180. It doesn't matter what angle ADB is.

If the figure is arranged differently, please clarify.
its 118 peoples!
