If is an acute triangle, all the angles should be acute angles.
180-38=142°
142-69=73°
So your answer is 69°, lovely~
Answer:
5.54 feet.
Step-by-step explanation:
Let h be the height of the pool and r be the radius of the pool.
We have been given that volume of cylindrical pool in Sunny Days Apartment building is 1200 cubic feet.
We have been given that the radius of the pool is 1.5 times its height. We can represent this information in an equation as:
Substituting equation (1) in volume formula we will get,
Substituting the given volume of pool in formula we will get,
Let us divide both sides of our equation by 2.25 pi.
Let us take cube root of both sides of our equation.
Therefore, the height of the pool is approximately 5.54 feet.
Left side is 22.
22 x 10 = 220
(20 - 6) x 12 = 168
6 x 20 = 120
220 + 168 + 120 = 508
Thank you very much.
