A great white shark swims 422 feet below sea level. If the horizontal distance from the shark to a sailboat is 348 feet, what is the angle of
elevation in degrees from the shark to the boat?

B.) 50°

Step-by-step explanation:

This is basically asking for the angle to the left of the right angle. Use the tangent ratio:

Insert values:

Use the inverse:

Insert this into a calculator:

Round to the nearest degree:

The angle of elevation is 50°.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
