The triangle is a right triangle, which means the Pythagorean Theorem can be used to find the length of the hypotenuse.
The Pythagorean Theorem is: a² + b² = c², where c is the hypotenuse of the triangle.

To find the length of the hypotenuse of this triangle, you'd plug the leg lengths into the theorem for a and b and then solve for c. The equation would be as follows.

5² + 8² = c²

To solve for c, first square 5 and 8:
25 + 64 = c²

Then collect the constants:
89 = c²

Lastly, take the square root of both sides:
9.434 ≈ c

The hypotenuse is approximately 9.4 cm.

Pythagoras' Theorem

a^2 + b^2 = c^2
where c is the length of the hypotenuse and a and b are the lengths of the other two sides
so

5^2 + 8^2 = c^2
