need some help with this yucky problem :)
from a ship offshore, the angle of elevation of a hill is 1.1 degrees. After the ship moves inland at 4.5 knots for 20 min, the angle of elevation is 1.4 degrees. How high is the hill? (1 knot = about 6080 feet per hour)
i found out that the boat with the 1,1 degree angle is 9120 ft from its second position with the 1.4 degree angle, but now im stuck :(

Sorry it's taking me so long to respond - phone rang.
And again, sorry, but I don't know how to solve this one o.0
It has something to do with the fact that in 20mins the angle changed .3 degrees, but I don't know how to incorporate that into an equation.
Alas, I cannot answer :'(
