A girl on top of a storey building 36m high dropped a N10.00 note on the ground below. If the angle of depression of the N10.00 note is 35°, how far is the money from the girl?
make a sketch
using trig.ratios
Sin\(\theta\) = \(\frac{opp}{hyp}\)
Sin35 = \(\frac{36}{hyp}\)
hyp = \(\frac{36}{sin35}\) = 62.76m
∴ the distance between the girl and the #10.00 note = 62.76m.
