Answer:

126 degrees

Explanation:

We are given BC is congruent to BE therefore BDE is congruent to BDC. We can use this to solve for p:

9p-81=5p-17

Move like terms to one side

4p=64

Divide 4 from both sides

p=16

Therefore:

BDC=9(16)-81

BDC=144-81

BDC=63

CDE=BDC+BDE

CDE=2(63)

CDE=126 degrees
