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°
It would be the first box, when multiplying exponents, you add the exponents and just keep the base. So it be 2^17
V=900m³
V=L*w*h
V=20*3*w
V=60*w
60*w=900
w=900/60
w=15m
