To find the length of the other leg of the right triangle, we can use the Pythagorean theorem which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.
Let's denote the length of the other leg as x.
Using the Pythagorean theorem, we have:
x^2 + 6^2 = 12^2
Simplifying this equation, we get:
x^2 + 36 = 144
Subtracting 36 from both sides:
x^2 = 108
Taking the square root of both sides:
x = √108
Simplifying the square root:
x ≈ 10.39 feet
Therefore, the length of the other leg is approximately 10.39 feet.
if a right triangle has a leg that is 6 feet long and the hypotenuse is 12 ft long how long is the other leg?

without simpliflying
If we do not simplify, the length of the other leg would be √108 feet.
a triangle has 20 and 30 on each side of length what is the last length
To find the length of the third side of the triangle, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Let's denote the length of the third side as x.
According to the triangle inequality theorem, we have two inequalities:
x + 20 > 30 (the sum of the third side and 20 is greater than 30)
x + 30 > 20 (the sum of the third side and 30 is greater than 20)
Simplifying these equations, we get:
x > 10 (subtracting 20 from both sides in the first inequality)
x > -10 (subtracting 30 from both sides in the second inequality)
Since x must be greater than both 10 and -10, the length of the third side could be any positive value greater than 10 or any negative value less than -10.
Therefore, without additional information, we cannot determine the exact length of the third side of the triangle.

a right triangle
If the triangle is a right triangle, we can use the Pythagorean theorem to find the length of the third side.
Let's denote the length of the third side as x.
Using the Pythagorean theorem, we have:
x^2 = 20^2 + 30^2
Simplifying this equation, we get:
x^2 = 400 + 900
x^2 = 1300
Taking the square root of both sides:
x ≈ √1300
Simplifying the square root, we get:
x ≈ 36.06 feet
Therefore, the length of the third side of the right triangle is approximately 36.06 feet.
