  • Height of tower can be taken as perpendicular
  • Base is already given

And we know


\\ \tt\hookrightarrow tan\theta=(Perpendicular)/(Base)


\\ \tt\hookrightarrow tan47=(P)/(30)

Answer:

cosine rule - cos =
(a)/(h)

Explanation:

Here the ladder is acting as hypotenuse and base as adjacent.

Formula: cosθ =
(adjacent)/(hypotenuse)
