Question

A triangle has side lengths 10, 15, and 7. Is the triangle acute, obtuse, or right? Explain

Answer 1

a^2+b^2=c^2

Answer 2

that is what I was thinking

Answer 3

7^2+10^2=15^2
When you use the Pythagoras they don't relate so it wouldn't be a right triangle

Answer 4

Now it's either going to be acute or obtuse and for it to be acute the hypotenuse of a right triangle would be longer than the hypotenuse which is 15 and since it's not then it's an obtuse triangle.

Answer 5

Yea that one was pretty easy I remembered from a couple of questions we did for the exams

Answer 6
