Answer:
Base of the ladder is 3 meters away from the building.
Step-by-step explanation:
Let's use Pythagoras theorem to solve.
Pythagoras theorem says,

Here let horizontal distance is "a''
Vertical distance of window is 4 m
So, b=4
The Rafi leans 5 m ladder against the wall. So, c=5.

Simplify it

Subtract both sides 16

Take square root on both sides
a=±3
So, base of the ladder is 3 meters away from the building.
The answer is 1/3 because I just took the test
Answer:
a) B
b) draw a closed circle right before 0.1 (where 0.083 would be)
c) 1/12
The resultant force would be 88.88 N at an angle of 43 degrees from the 100 N force.
