<span>The height (h) of a triangle is 4 in. greater than twice its base (x): h = 2x + 4
</span>The area of the triangle is no more than 168 in.2: A ≤ 168 in²
The area of the triangle is A = x*h/2
Hence x*h/2 ≤ 168 in²
Substitute h in the formula for the area:
h = 2x + 4 = 2(x + 2)
x*h/2 ≤ 168 in²
x * 2(x + 2)/2 ≤ 168
x * (x + 2) ≤ 168
x² + 2x ≤ 168
x² + 2x - 168 ≤ 0
Using the formula for quadratic equation:

(b) Angle with East direction is 
Explanation:
Force by Jack in vector form
Force by Jill in Vector form is given by
Force by Jane is
Net force is:
Hence
The net force will be given by
Since 
and 
The direction of net force is:
Since and
The angle with East direction is
Net force exerted on the donkey is in the south-east direction. So, the angle of net force from the east direction is and it is 
from the south.
