use the Pythagorean Theorem to find the unknown side length, round to the nearest tenth. Right side: 15 Bottom: 3

Answer 1

To find the unknown side length, let's label the two given sides:

- The length of the right side is 15.
- The length of the bottom side is 3.

Now, let's find the length of the unknown side using the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Let the unknown side length be represented by x.

Using the theorem, we have:

x^2 = 15^2 + 3^2
x^2 = 225 + 9
x^2 = 234

To find the value of x, we take the square root of both sides:

x = √234

Rounding to the nearest tenth, the length of the unknown side is approximately 15.3.
