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 =  = , thus

x = ( ) ≈ 65°

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

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
