Using the pythagorean theorem, find the length of a leg of a right triangle if the other leg is 8 foot long and the hypotenuse is 10 feet long?

⓵ The pythagorean theorem is calculated by using this formula : a² + b² = c²

“a” is the length of one of the legs
“b” is the length of the other leg
“c” is the length of the hypotenuse

⓶ Now that you have the formula, replace the letters in the formula with the information that you have :

8² + b² = 10²

⓷ Now that this is done, you need to isolate the “b²” in order to find the length of the other leg of the triangle :

8² + b² = 10²
-8² -8²

↓

b² = 36
√b² √36

↓

b = 6

So the final answer is : the length of the other leg of the triangle is ↠ 6 feet

I really hope this helped, if there’s anything just let me know! ☻
