A ladder 10 feet tall is leaning against a building. The top of the ladder is 8
feet above the ground. How far from the building is the foot of the ladder?

6 feet

Step-by-step explanation: You can solve this by solving the Pythagorean Theorem:

c^2 = a^2 + b^2

In this case, the hypotenuse (C) of the equation is 10, and one of the legs (A) is 8. You then solve the following steps

10^2 = 8^2 + b^2

100 = 64 + b^2

36 = b^2

6 = b

i used to know but i learned it a long time ago sorry

step-by-step explanation:

i believe the answer is the polygon, heptagon.
