Hello!
The ground, building and ladder are making a triangle, and since the ladder is tilted and is the longest side, it is the hypotenuse. We know how long the floor (leg) and ladder (hypotenuse) are. We need to solve for how tall the third floor window is from the ground. To do so we will use the Pythagorean Theorem (c²-b²=a²).
100-25=75
√75≈8.66
The third story window is about 8.66 meters from the ground.
I hope this helps!
