Answer:570.54 N
Explanation:
Given
mass of man=76 kg
![\theta =50^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D50%5E%7B%5Ccirc%7D)
As man is standing over inclined building therefore
its weight has two components i.e. sin and cos component
Force perpendicular to inclined wall
![F=mgcos\theta =76\times 9.8\times \sin 50](https://tex.z-dn.net/?f=F%3Dmgcos%5Ctheta%20%3D76%5Ctimes%209.8%5Ctimes%20%5Csin%2050)
F=570.54 N
