Answer:
4777.28 N
Step-by-step explanation:
The gravitational force down the slope is given by the formula;
(mass *g * sin θ )
where;
θ is the angle of inclination of the slope
g is the gravitational pull
We plug in the given values into the above expression;
(4,000 x 9.8 x sin 7) = 4777.28 N.
The frictional force must equal to 4777.28 N (pointing up the slope).
6*3=18
5*3=15
6*4=24
5*4=20
then you would add the columns and you would get 1,904
It would be easier to show you.

Given
The tower is at a height of 
the angle of depression is 
Suppose the surfer is x ft away from the base of the tower

Therefore, the surfer is at a distance of 19.31 ft from the base of the tower.
