The only formula you need is one that we're sure you already know.
In every right triangle,
(leg-A)2 + (leg-B)2 = (hypotenuse)2
In this right triangle, the legs are equal, and the hypotenuse is 10.
(leg)2 + (leg)2 = (10)2
2 times (leg)2 = 100
Can you take it from there ?

If the lengths of the two sides of a right triangle on either side of the 90 degree angle are 3 inches and 2 inches what is the length of the remaining side the hypotenuse?
The formula is A-squared + B-squared = C-squared where A and B are the sides and C is the hypotenuse. Given the values of A and B as 3 inches and 2 inches we can use the formula: 3-squared (9) + 2-squared (4) = 13. The length of the hypotenuse is the square root of 13 (3.6055512).

What is the length of the hypotenuse of a right triangle that has a base of 5 inches and a height 12 inches?
Hypotenuse^2 = base^2 + height^2, substitute the given values Hypotenuse^2 = 5^2 + 12^2 Hypotenuse^2 = 25 + 144 Hypotenuse^2 = 169 Hypotenuse = √169 Hypotenuse = 13 Thus, the hypotenuse is 13 inches.
