The measure of angle is 70 degrees
The complete question is an illustrates the concept of angle bisector;
Where:
, and line PC bisects
Because line PC bisects , then it means that the measure of RPD is twice the measure of CPD:
So, we have:
Substitute
Divide both sides by 2
Apply symmetric property of equality:
Hence, the measure of angle is 70 degrees
