Answer:
Θ = 18.2°
Step-by-step explanation:
Using the law of sines in the triangle
= ( cross- multiply )
8 × sinΘ = 5sin30° ( divide both sides by 8 )
sinΘ = = 0.3125
Θ = (0.3125) ≈ 18.2° ( nearest tenth )

Answer:
The pump fill the pool in 3/5 hours
Step-by-step explanation:
From noon to 1/4 hours later, the pool goes from 1/3 to 3/4 full. That's means that the pool fill X quantity in 1/4 hours, where X is calculate as:
So, the constant rate R can be calculated as:
That means that every hour the pool can be fill 5/3 full, so if we want to know how many hours is needed to fill the poll one time, we can write the following equation:
Where t is the time required to fill the pool. Solving for t we get:
t = 3/5 hours
so, the pump fill the pool in 3/5 hours or 36 minutes with a constant rate of 5/3.
