Answer: D; 3 - 7 = -4
Explanation: Since 3 is the largest value in this equation and the arrow is going to the left (starting at a positive and stopping at a negative), you count backwards 7, which would be subtracting 3 from 7 in this case.
Subtract 180 - 34 = 146
You know ∠BPD adds up to 146°
Since
bisects ∠BPD, you know that ∠BPC and ∠CPD are equal to each other.
Divide 146 by 2 = 73
m∠CPD = 73°
