1. The lengths of the three sides of a triangle are given. Classify each triangle as acute, right, or obtuse.

Question

NUMBERS: 30, 40, 50.

I'm confused by this question, could someone help/explain what it is asking.

Answer 1

well, I happen to know that

3^2 + 4^2 = 9+16 = 5^2

so 30^2 + 40^2 = 50^2

so that is a right triangle.

Answer 2

How did you get this? where did the numbers come from and what formula did you use?

Answer 3
