To estimate the height of a mountain, two students find the angle of elevation from a point (at ground level)
b
=
640
meters from the base of the mountain to the top of the mountain is
β
=
47
∘
. The students then walk
a
=
2350
meters straight back and measure the angle of elevation to now be
α
=
40
∘
. If we assume that the ground is level, use this information to estimate the height of the mountain.
