To find the missing side of the triangle, we can use 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. In this case, if the two given sides are 7 cm and 13 cm, we can use the formula (a^2 + b^2 = c^2), where a and b are the given sides and c is the missing side (the hypotenuse). Plugging in the values, we get (7^2 + 13^2 = c^2), which simplifies to (49 + 169 = c^2), or (218 = c^2). Taking the square root of both sides, we find that the missing side is approximately 14.76 cm.

Need the angle between those two sides, or some more info.

Imagine taking a 1 inch tooth pick and a 2 inch toothpick. Now line up the tips and you

can make tons of angles. If you joined the outer tips of your toothpicks you would have a triangle. Can you see that you can have many different sides lengths depending on the angle between them?
