Practice makes perfect

To find the missing side of the triangle, we will use the Pythagorean Theorem.

In the formula, a and b are the legs and c is the hypotenuse of a right triangle. We are given a triangle with a=6 and c=13. Let's substitute these values into the formula.

a^2+b^2=c^2

SubstituteII

a= 6, c= 13

6^2+b^2= 13^2
