Answer 1

Answer:

Step-by-step explanation:

Object distance is 350 ft from the foot of the sky scrapper

The height of the scrapper is 750ft

The angle of elevation= θ

The angle of elevation is the angle between the line of sight of the observer and the direction of elevation to the top of the sky scrapper

we are give the opposite of the angle of elevation which is the height of the sky scrapper 750ft

And we are given the adjacent which is the object distance 350ft.

Using trigonometric triangular formular

So, using tangent

Tanθ=opposite / adjacent

Opposite =750

Adjacent =350

Tan θ= 750/350

Tan θ=2.1429

θ=arctan(2.1429)

θ=64.98

So the angle of elevation is 65° approximately which is the first option

Answer 2

Answer:

about 65°

Step-by-step explanation:

Using the tangent ratio in the right triangle

let x be the angle of elevation ( measured up from the horizontal )

tanx = $\frac{opposite}{adjacent}$  = $\frac{750}{350}$, thus

x = $tan^{-1}$ ( $\frac{750}{350}$ ) ≈ 65°
