39 degrees 
Step-by-step explanation:
Right triangle 
40 ft tree = opposite side 
50 feet = adjacent side
tan (angle) = opp / adj = 40 /50 
arctan (40/50) = 38.66 degrees ~ 39 degrees

This is a quadratic formula with a general form of a²x + bx + c = 0. For quadratic equations, we can solve for its two roots using the quadratic formula shown in the attached picture.
a = -3
b = -4
c = -4
x = [-(-4) + √(-4)² - 4(-3)(-4)]/2(-3) = 
<em>2 + √-32/2</em>x = [-(-4) - √(-4)² - 4(-3)(-4)]/2(-3) =
<em> 2 - √-32/2</em>
