Question

A building meets the ground at a right angle. The top of a 10-foot ladder is placed against the bottom edge of a window in the building, and the base of the ladder is placed 6 feet from where the building meets the ground. Draw diagram that represents this situation. How far up from the ground is the bottom edge of the window?

Answer 1

Answer:

8 ft

Step-by-step explanation:

Use pythagorean theorem. $a^{2}+b^{2}=c^{2}$. Put 10 and 6 into the equation as b and c.

$a^{2}+6^{2}=10^{2}$

$a^{2} =100-36\\a^{2}=64\\a=8$

Therefore, the answer is 8ft.

A diagram is attached. Sorry it's kinda messy.
