its not urgent im just trying to bring my grade up and i just need some help
ill give brainliest to the correct answer
i have to put this on art cuz nobody will answer on mathematics

Yes, number 2 would make a right triangle

Explanation:

So, you have to use pythagorean and theorem, which is a^2 + b^2 = c^2

So the equation would be 15^2___ 9^2 + 12^2

After squaring them and doing the maths, it would be 225___ 91 + 144

144 + 91 = 225, so since they're equal, it would be a right triangle.

If it were less than, it would be acute, and if it were greater than, it would be obtuse

the correct answer would be "the amiens cathedral"
