Question

a ladder set a wall makes an angle theta with the horizontal . when its foot is pulled away from the wall the distance 'p' it slides a distance 'q' down the wall making an angle fy with the horizontal . show that p by q =cos theta minus cot fy by sin fy minus sin theta.

Answer 1

answer

see the above picture

Answer 2

Answer: In the question given below that p,q are on the horizontal angle.

Distance between both = p×q/

So , let's P be 50 and Q be 40

Hence, 50×40/

= 2000/

= 20° is answer

Step-by-step explanation: Thank you I hope that my answer will help you.
