Answer:
9ft
Step-by-step explanation:
The base area of the storage is its volume divided by height

Pairs of corresponding angles have the same measure.
D, B, and A are collinear. Yes they are coplanar because they all lay on the same plane. And I don’t understand the last question
Answer: F=140
Step-by-step explanation:
720=(x-60)+(x-40)+(x-20)+130+120+110
720-130-120-110=3x-120
360=3x-120
360+120=3x
480=3x
480/3=x
160=x
F=160-20
Next problem
102+31+x=180
133+x=180
x=180-133
x=47
