A seagull’s elevation is 14 feet above sea level. A shark is swimming 56 feet below sea level. Which expression correctly models the difference in elevation between the seagull and the shark?

see below

Step-by-step explanation:

Above the sea level is positive  +14

Below the sea level is negative  - 56

To find the distance between them

14 - (-56)

14 + 56

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

it would rotate about 180 degrees.
