we know that
The function composition is equal to
(r ∘ s )(x) = r(s(x))
In the function r(x) substitute the variable x by the function s(x)
so
For x=3
substitute the value of x=3 in the function composition
From the top of a vertical pole the angle of depression to Ian standing at the foot of the pole is 43°. Liam is on the other sid
2 answers:
The height of the pole based on the angle of depression given is 62.2m.
<h3>How to calculate the height?</h3>From the information given, Liam is on the other side of the pole, and the angle of depression from the top of the pole to Liam is 52° and the boys are standing 58 m apart.
Let the height = h
It should be noted that:
tan = opposite/adjacent
tan 43° = 58/h
tan 43° × h = 58
0.9325 × h = 58
0.9325h = 58
h = 58/0.9325
h = 62.2m
