Tony is standing at sea level. from his location, the angle of elevation of the top of blue mountain is 25°. staying at sea level, he walks 200 yards toward the mountain. the angle of elevation of the top is now 30°. find the height of blue mountain. round intermediate results to 3 decimal places and the final answer to 1 decimal place.

the height of blue mountain is yards

h = 1558.8

Step-by-step explanation:

Let x be the distance from the vertex of the 30 degree angle to the base of Blue mountain.

Tan (30) = h/x                       Multiply both sides by x.

x * Tan(30) = h

Tan(25) = h/(x + 200)           Multiply x + 200 on both sides.

(x + 200) * Tan(25) = h

Now you have 2 equations both equal to h. The two sides can be equated to each other.

x*tan(30)  = (x + h) * Tan(25)         Divide both sides by tan(25)

x*tan(30)/tan(25) = x + 200          Find Tan(30)/Tan(25)

Tan30 / tan(25) = 1.23813 so

1.23813 x = x  + 200                      Subtract x from both sides.

0.23813x = 200                             Divide both sides by 0.23813

x = 200/0.23813

x = 839.99

That is not the answer you have been asked for. What you need is h.

Tan(30) = x / h                                Multiply both sides by h

h*tan(30) = x                                   Divide both sides by tan(30)

h = x/tan(30)

h = 839.99/tan(30)                        Tan 30 = 0.57735

h = 839.99/0.57735

h = 1558.8
