Answer:
60
Step-by-step explanation:
<C+<D = 180 since they form a straight line
5x+20 +3x = 180
8x+20 = 180
Subtract 20 from each side
8x+20-20 = 180-20
8x = 160
Divide by 8
8x/8 = 160/8
x = 20
We want to find angle D
<D = 3x= 3*20 = 60
Tape dispenser the others are too heavy
Formula for volume L x W x H
We got them all.
So, 30 x 15 = 450.
450 x 12 = 5400
The aquarium is 5400^2 inches
