Bob is flying his kite while standing in his yard and the kite is flying over
his friends house. He know the string is 75 ft long and the angle the string
where he is holding it makes a 35° angle with the ground. How far is Bob
from his friends house?
43 ft
61 ft
75 ft
35 ft

Answer 1

Ground distance of Bob from his friends house = 61 ft (Approx)

Explanation:

Given:

Length of string = 75 ft

Angle with the ground = 35°

Find:

Ground distance of Bob from his friends house.

Computation:

Using trigonometric application:

⇒ Cos
`\theta` = Base / Hypotenuse

⇒ Cos 35° = Base / 75

⇒ 0.819 = Base / 75

⇒ Base = 61.425 ft

Ground distance of Bob from his friends house = 61 ft (Approx)
