Answer:
Referring figure, AB = pole AC = cable,
BC = distance between pole and cable = a
∠B = 90
o
, ∠C = θ
∴ tanθ =
BC
AB
=
a
AB
∴ AB = a tanθ
∴ Height of the pole is a tanθ

Answer:
- tan teta= opposite side by adjacent side
- tan teta =h by y
- tan(90 - teta)
- (tan×cot) teta = h by y ×h by x
- 1=h² by xy
