Answer:
Explanation:
This is a trick question, about the red marks again. those marks are important b/c they tell you that the lengths are the same, so that the angles MUST also be the same. That is , D and E are equal
so set up your equations with that info
180 = 84 +2p
now use your algebra skillz to solve
180-84 / 2 = p
96/2 = p
48 = p
see??
