Question

given the information in the picture which trigonomic identity can be used to solve for the height of the blue ladder that is leaning against the building​

Answer 1

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

And we know

$\\ \tt\hookrightarrow tan\theta=\dfrac{Perpendicular}{Base}$

$\\ \tt\hookrightarrow tan47=\dfrac{P}{30}$

Answer 2

Answer:

cosine rule - cos = $\frac{a}{h}$

Step-by-step explanation:

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

Formula: cosθ = $\frac{adjacent}{hypotenuse}$
