Question 408082
a weather balloon ascends at a rate of 3.86 km/h while moving at an angle of 71.8 degrees with the ground.
 at the end of an hour what is the horizontal travel (x) of the balloon?
:
At the end of an hr the balloon will be 3.86 km high
:
Use the tangent of 71.8 degrees, side opposite = 3.86, side adjacent = x
:
tan(71.8) = {{{3.86/x}}}
x = {{{3.86/tan(71.8)}}}
x = 1.27 km is the horizontal travel
