Answer:

The answer to your question is Ariel is correct, x = 27 ft

Step-by-step explanation:

Data

angle = Ф = 47°

Adjacent side = 25

Opposite side = x

Process

1.- To solve this problem, we must use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.

            tan Ф = Opposite side / Adjacent side

- Solve for Opposite side

            Opposite side (x) = Adjacent side x tan Ф

-Substitution

                                      x = 25 tan 47

                                     x = 25 (1.0724)

-Result

                                    x = 26.8 ≈ 27 ft

Ariel is correct

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
