4.55 ft assuming the stem is perpendicular to the ground. Hypotenuse would be 5.45
The base of 3 is not part of the stem
5.45 sq = 4.55 sq + 3 sq
Assuming the stem is perpendicular to the ground, call the distance from the ground to the break h. Then, the hypotenuse of the right triangle formed will have length 10 - h. Using the Pythagorean theorem:
h^2 + 9 = (10 - h)^2
h^2 + 9 = 100 -20h + h^2 //canceling out the h^2 on each side gets
9 = 100 - 20h
Solving the linear equation reveals h=4.55
