What kind of a triangle has sides of 8 and 13 and 15?

The triangle with sides measuring 8, 13, and 15 is a scalene triangle, as all three sides have different lengths. To determine the type of triangle based on angles, we can use the Pythagorean theorem. Since (15^2 = 225) and (8^2 + 13^2 = 64 + 169 = 233), and 225 is less than 233, the triangle is acute.
