Answer:
Step-by-step explanation:
The figure has been attached, to complement the question.
Given that J is the centroid, it means that J divides sides CD, DE and CE into two equal parts respectively and as such the following relationship exist:
Solving (a): DG
If , then
Make DG the subject
Substitute 52 for DE
Solving (b): GE
If , then
Solving (c): DF
So:
Solving (d): CH
Solving (e): CE
If , then
If the equation for volume is V=l*w*h, you can plug in all of the information you know. When you do this, the equation becomes 1440=15*12*h, or 1440=180*h (because 15*12=180). You can divide both sides by 180 to get h. 1440/180=8, do the depth of the pool is 8 ft. You can also check this answer by making sure that 15*12*8 is equal to 1440 (which it is). I hope this helped!
