Step-by-step explanation:

The angle of depression is measured from the horizontal line of sight, not from the vertical.

The correct equation is:

tan(47°) = 25 / x

x = 25 / tan(47°)

x = 23 feet

Answer:

Incorrect angle; 23 feet

Step-by-step explanation:

She has marked the angle incorrectly

Angle of depression is marked between the line of sight and the hypotenuse

The angle she should use is:

90 - 47 = 43

tan(43) = x/25

x = 25tan(43)

x = 23.31287715
