Question

Calculate the angle that the ladder makes with the ground using a trigonometric ratio.

Answer 1

Answer:

Consider the ladder and wall system as the right angled triangle, such that length of wall (W) till the ladder reaches be the perpendicular= 15 cm and angle (G) made by ladder (L) with the ground  is 30∘,  

and length of ladder be the Hypotenuse.

Thus, sinG=HP​

sin30=LW​

21​=L15​

L=30 m=3000 cm

Answer 2

If a ladder is x feet long, how high up a wall can it safely reach?

Would a 51-foot ladder be long enough to climb a 50-foot wall? Sketch a graph and find your answer using a trigonometric ratio. If you wanted to safely climb a 50-foot wall, what’s the shortest ladder you’d be willing to use?

If you were 1 foot shorter, could you use a ladder that’s 1 foot taller?
