Review your basic trig functions. The height is
1.15 + 95.5tan31.5°
A boy is trying to find the height of a tree. When he stands 95.5 metres away
from the tree (the distance D in Figure 2) the angle shown as è in Figure 2 is
31.5°. The boy’s eyes are 1.15 m from the ground (h in Figure 2). What is the
height of the tree? You can assume that the ground is level and you should
give your answer to an appropriate number of significant figures/decimal
places.
