Question 715244: Due to a storm, a flagpole broke at a certain point. The top part tipped over like a hinge, with the tip hitting the ground at a point 20 feet from the flagpole's base.
The flagpole was rewelded, but another storm broke it again at a point 5 feet lower than the previous break. And, this time the tip hit the ground at a point 30 feet from the base.
How tall was the flagpole?

Let the broken part length be y
let the remaining lenngth be x
distance from base of pole = 20ft
they form a right triangle
by Pythagoras theorem
Second condition
it breaks 5feet below
The broken part length = y+5
The remaining part length =- x-5
distance from base of pole = 30 ft
10x+10y=500
/10
x+y= 50
But x+y is the length of the flag pole
