Given that <APD=4x+123,<DPC=-5x-3 and <CPB=6x+105,find the measure of <DPC.

Answer 1

If this is a triangle then they sum to 180 degrees

4x+ 123 -5x-3 + 6x + 105 = 180

5x + 225 = 180

find x and then substitute the value into -5x -3 to find <DPC

Answer 2

Thanks John!

Answer 3

How could it be a triangle with P in the middle of all three angles?
I think we are missing information.

Answer 4

There is no info missing

Answer 5
