a surveyor wanted to measure the height
of a mountain peak. she took a straight
road leading to the mountain and
measured the angle of elevation from point
a on the ground to the top of the mountain
das 33º. she drove 0.5 km further towards
the mountain and measured the angle of
elevation again as 40°.
a make a labelled diagram that
represents the situation.
b find the height of the mountain to the
nearest metre.
