Math Problem Statement

Find the length of the third side. If necessary, write in simplest radical form. One leg is 3√3, and the hypotenuse is 6.

Solution

The problem shows a right triangle where one leg has a length of 333\sqrt{3} and the hypotenuse has a length of 6. We are tasked with finding the length of the third side, which is the other leg of the triangle.

Using the Pythagorean theorem:

The Pythagorean theorem states that for a right triangle:

a2+b2=c2a^2 + b^2 = c^2

Where:

  • aa and bb are the lengths of the legs, and
  • cc is the length of the hypotenuse.

Given:

  • One leg a=33a = 3\sqrt{3},
  • Hypotenuse c=6c = 6.

We need to find the length of the other leg, bb.

Step 1: Apply the Pythagorean theorem

(33)2+b2=62(3\sqrt{3})^2 + b^2 = 6^2

Simplify both sides:

(33)2=9×3=27(3\sqrt{3})^2 = 9 \times 3 = 27 62=366^2 = 36

So the equation becomes:

27+b2=3627 + b^2 = 36

Step 2: Solve for b2b^2

b2=3627b^2 = 36 - 27 b2=9b^2 = 9

Step 3: Solve for bb

b=9=3b = \sqrt{9} = 3

Thus, the length of the third side is 3.
