Assuming the house is parallel to the ground, your triangle is made up by the house, the ground, and the ladder. Using sin(x) = opposite/hypotenuse on the angle 70 degrees, you would have sin(70) = 20/x (because 20 is the side opposite of the angle connecting the ladder and the ground)
--> simplify sin(70) * x = 20 --> x = 20 / sin(70
--> substitute (and make sure your calculator in in degrees) x= 21. 284
Answer:
Solution:
<u>We know that:</u>
- Capacity = 2,500 gallons
- Hose = 25 gallons/minute
Solution:
- 25 gallons = 1 minute
- => 25x gallons = x minutes = 2500 gallons
- => 25x = 2500
- => x = 100 minutes
Hence, it will take 100 minutes to fill the pool.

Answer:
78
Step-by-step explanation:
