Question

Find the length of the hypotenuse of a right triangle where the perpendicular sides are 3 in. And 4in. In length

Answer 1

5 inches

Explanation:

To find the hypotenuse or any side of a right triangle, use the Pythagorean theorem. This is
`a^2+b^2=c^2` where a and b are the perpendicular sides and c is the hypotenuse. So, plugin 3 and 4 for a and b. This gives 9+16=c^2, which is equal to 25=c^2. Then, take the square of both sides to get c=5.

Another way to solve this is to know the triples. Triples are right triangles that have integers for all of their sides. The triple 3,4,5 is the smallest and most common triple.
