Ответ:
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
Ответ:
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
