Question 280562
The Sine and Cosine Ratios
A certain jet is capable of a steady 20 degree climb.  How much altitude does the jet gain when it moves 1km throughthe air? Answer to the nearest 50m.
-----------------
1 km = 1000 meters = the hypotenuse
Vertical change = 1000*sin(20) = 342 meters
--> 350 meters to the nearest 50
