Question

Please I am really Confused If you can help that would be great!

Answer 1

Incorrect angle; 23 feet

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

Answer 2

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

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
