Question

This set of 3 numbers are measurements of a right triangle. 8, 7, 5 true or false?

Answer 1

False.

Pythagorean theorem is the equation we use to check this.

Pythag' looks like this: A² + B² = C²

So 5² = 25

7² = 49

25 + 49 = 74

The root of 74 is 8.6....NOT 8 even. (8² = 64 anyways...)  

As such, the 3 numbers listed do NOT make a right triangle.

Hope I could help!! :)
