To determine the height of a television tower, a person stands 135 ft from its base and determines the angle of elevation to the top of the tower to be 38 degrees. what is the height of the tower?

  105.5 ft

Step-by-step explanation:

The tangent ratio is the ratio of the side opposite an angle to the adjacent side in a right triangle. Here, the side opposite the angle is the tower height, and the adjacent side is the distance to the tower. Then the appropriate relationship is ...

  tan(38°) = (tower height)/(135 ft)

Multiplying by the denominator gives ...

  tower height = (135 ft)·tan(38°) ≈ 105.473 ft

The height of the tower is about 105.5 feet.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
