Answer:

cosine rule - cos = [tex]\frac{a}{h}[/tex]

Step-by-step explanation:

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

Formula: cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex]
  • Height of tower can be taken as perpendicular
  • Base is already given

And we know

[tex]\\ \tt\hookrightarrow tan\theta=\dfrac{Perpendicular}{Base}[/tex]

[tex]\\ \tt\hookrightarrow tan47=\dfrac{P}{30}[/tex]
