.
First, determine the height of the tree from the ground to the break.
Let x = height of the tree from the ground to the break
then applying Pythagorean theorem
x^2 + 15^2 = 25^2
x^2 + 225 = 625
x^2 = 400
x = sqrt(400)
x = 20 feet
.
Second, determine the height of tree from the break to the top
Let y = height of tree from the break to the top
then applying Pythagorean theorem
20^2 + 48^2 = y^2
400 + 2304 = y^2
2704 = y^2
sqrt(2704) = y
52 feet = y
.
Height of tree = x+y = 20+52 = 72 feet
