A30-meter high building sits on top of a hill. the angles of elevation of the top and bottom of the building from the same spot at the base of the hill are measured to be 55 degrees and 50 degrees. how high is the hill to the nearest meter?

Explanation:

According to the given data, we can draw a figure (Please refer the attachment below)

Building's height = 30 meter

Angle of elevation from a spot to the top of the building = 55 degrees

Angle of elevation from the spot to the top of the building = 50 degrees

To find the height of the hill, we need to use the formula,

then,

  .... (1)

Similarly,

  .... (2)

(1) = (2) becomes

[tex]\Rightarrow [tex] 1.428h  = (30 + h)1.192

1.428h  =  35.76 + 1.192h

1.428h - 1.192h = 35.76

0.236h = 35.76

h = 151.52 meter

Therefore, the hill highs 151.52 meter.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
