Explanation:

Given that,

Force of gravity acting on the person, F = mg = 850 N

The roof is on the 20 degrees slope with the surface. We need to find the magnitude of normal force of the roof on the worker. It can be calculated as :

$F_N=mg\ cos\theta$

$F_N=850\times \ cos20$

$F_N=798.73\ N$

So, the normal force of the roof on the worker is 798.73 N. Hence, this is the required solution.
