To find the height of a tower, a surveyor positions a transit that is 2 meters tall at a spot 35 meters from the base of the tower. She measures the angle of elevation to the top of the tower to be 37°. What is the height of the tower, to the nearest meter?

The answer to your question is 28.37 m

Step-by-step explanation:

Data

height of the transit = 2 m

distance to the tower = 35 m

angle = 37°

Process

To solve this problem 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 = Adjacent side x tan Ф

1) Substitute values

                   Opposite side = 35 x tan 37°

2) Simplification

                    Opposite side = 35 x 0.7536

                    Opposite side = 26.37 m

3) Calculate the height of the tower.

                    Height = 26.37 + 2

                                = 28.37 m

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
