Related Rate (Calc 1): A jet ascends at a 10 degree angle from the horizontal with an airspeed of 550 mi/hr. How fast is the altitude of the jet increasing? If the sun is directly overhead, how fast is the shadow of the jet moving on the ground?

I'm not really sure how to go about working this one. I know that if I froze time at 1 hour I would have a right triangle with a hypotenuse of 550 miles, which I could then use along with the law of sines to find the lengths of the other sides, but I have no clue how to find rate the altitude is increasing.
