Tony is standing at sea level. from his location, the angle of elevation of the top of blue mountain is 23°. staying at sea level, he walks 220 yards toward the mountain. the angle of elevation of the top is now 27°. find the height of blue mountain. round intermediate results to 3 decimal places and the final answer to 1 decimal place.

559.2 yards.

Step-by-step explanation:

Let the height of the mountain be x yards and the distance from the second location to the base of the mountain be y yards.

Then we have the equations:

tan 27 = x/y

tan 23 = x / (220 + y)

From the first equation  y =  x/ tan27 so substituting in the second one we have:

tan 23 =  x / (220 + x / tan 27)

Cross multiply:

x = 220 tan23 +  x tan 23 / tan 27

x =  93.384 + 0.833 x

x - 0.833x = 93.384

x = 93.384 / 0.167

x = 559.2 yards to 1 dec place (answer).
