Homework Help: Precalculus

An observer 2 km from the launching pad observes a vertically ascending missile at an angle of elevation of 21 degrees. 5 seconds later the nagle has increased to 35 degrees. What was its average speed during this interval? If it keeps going vertically at the same average speed, what will its angle of elevation be 15 seconds after the first sighting?

I've calculated that the length the missile travelled during the 5 secs is .63 km. I don't know where to go from here..thanks for the help :)
