Determine PCD and CPD
First, we need to calculate CPD
Since DPA is a straight line and CPA = 100;
We have that:
--- angle on a straight theorem
Substitute 100 for CPA

Subtract 100 from both sides


Next, we calculate PCD
We have that:
--alternate angle
In triangle PCD
--- angles in a triangle
Where

So, we have:


Subtract 136 from both sides
