Any angle with a square is a right angle (90°)
therefore
90-a = b.

90-40 = 50.
b = 50.

Answer: 11.7 cubic feet

Step-by-step explanation:

Since,

$62.5 \text{ lb} = 1\text{ cubic feet}$

$\implies 1 \text{ lb} = \frac{1}{62.5}\text{ cubic feet}$

$\implies 731.25\text{ lb} = \frac{731.25}{62.5}\text{ cubic feet}$

$\implies 731.25\text{ lb} = 11.7 \text{ cubic feet}$

Thus, the tank hold 11.7 cubic foot of water.

One end of a ramp is raised to the back of a truck 5 feet above the ground. 1 point

sveta [45]

Answer:

38.7°

Step-by-step explanation:

You are basically looking at a triangle with a 90° angle (check picture).

Since we are looking for the ramp's angle and are given the length of the opposite and the hypothenuse, we have to solve the following equation:

$sin (\alpha) = opposite / hypothenuse= 5 ft/8ft$

which is equivalent to

$\alpha = sin^{-1}(5/8)\approx 38.7\deg$
