Question

precalc wiz??
you are in a hot air balloon and it has a 16 degree angle of elevation from a point 100 km away, then it rises to have an angle of elevation of 33 degrees from the same point, find how high it rose

Answer 1

I'll assume the rise is vertical




using sine rule \[\frac{h}{\sin17} = \frac{100}{\sin57}\]

\[h = \frac{100\times \sin17}{\sin(57)}\]

h = 34.86km

strange answer,,,,
