Question

Can you tell the angle measures of a triangle? I'll draw the triangle.

Answer 1

Options: 30, 60, 90 -or- they cannot be determined. I know that the triangle looks like a 30 60 90 triangle, so that's how I narrowed down my options, but I don't think you can mathematically prove it can you?

Answer 2

Since it is not indicated as a right triangle, I would test to determine if it is.

Answer 3

It is a right triangle so the answer is yes!

Answer 4

regular sin cos tan function can be used to find the angles.

Answer 5

Thank you!

Answer 6

You can prove it is a right triangle in that the hypotenuse squared is equal to the sum of the sides squared, and sure enough 588 = 588

Answer 7

Oh, okay so it's just a Pythagorean theorem problem. I get it now. Thank you so much!

Answer 8

You are welcome, I am sure you probably should mention that Pythagorean equation was used and is the basis of your conclusion.
