Question 1136488: At distance x from the base of a building, the angle of elevation to top of the building is 19 degrees. The angle of elevation is 39 degrees if you walk 13 ft closer to the building. There is a 10 ft antenna on top of the building. Find the height from ground to the top of the antenna.
You can put this solution on YOUR website! If one draws this, tan 19=y/x and tan 39=y/(x-13), y being the building's height.
x tan 19=x tan 39-13 tan 39
x (tan19-tan 39)=-10.53
x(-0.4655)=-10.53
x=22.62'
y=7.79'
So the height to the top of the antenna is 17.79'
