Question

l will MARK BRAINLIST

a ladder of length 15√2m reaches a window 15 M high find the inerination of the ladder with the ground

Answer 1

Hope you know the basics of trigonometry,

in this problem the altitude is 15 and the hypotenuse is 15√2

we know that sin¤ is altitude upon height

sin¤ = 15/15√2
= 1/√2

we know that the value of 1/√2 in trigno is sin 45

So, the angle will be 45 degrees.

Answer 2

Given, Length of ladder = 15√2m.

Given, Height of window = 15 m.

We know that sin θ = opp/hyp

⇒ Sin θ = (15/15√2)

⇒ Sin θ = (1/√2)

⇒ sin θ = sin 45

⇒ θ = 45°.

Therefore, the inclination of the ladder with the ground = 45°.

Hope this helps!
