A right trangle with side of 12 and an hypotenuse of 20 what is the missing length round to the nearest tenth if needed
To find the missing length in a right triangle, you 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 lengths of the other two sides.
In this case, you are given the length of one side, 12, and the length of the hypotenuse, 20. Let's call the missing length x.
According to the Pythagorean theorem, we have:
12^2 + x^2 = 20^2
Simplifying, we get:
144 + x^2 = 400
Subtracting 144 from both sides:
x^2 = 400 - 144
x^2 = 256
Taking the square root of both sides:
x = √256
x = 16
Therefore, the missing length is 16.
