Answer:
The sum of the interior angles of a triangle is always 180 degrees. The exterior angle is the angle between any side of a shape, and a line extended from the next side. The sum of an exterior angle and its adjacent interior angle is also 180 degrees.
Estimate of 428,731 - 175,842 = 400,000 - 200,000 = 200,000
Answer:
10400 lb
Step-by-step explanation:
First find the volume of the water in the pool: It is V = (length)(width)(height).
Here, V = (25 yds)(10 yds)(2/3 yd), or (500/3 yds³.
Then multiply this result by the unit rate (62.4 lb / ft³).
The result is 10400 lb. This is the weight of the water in the pool.
