you can solve by checking with the Pythagorean theorem (a^2 + b^2= c^2)
24 and 45 are the legs because the hypotenuse is the largest side so they will be substituted for a and b. if c is equal to 51 then it would be a right triangle
24^2 + 45^2= c^2
576 + 2025 = c^2
2601 = c^2
51 = c
because c = 51 and 51 was the hypotenuse on the triangle previously mentioned 24 45 51 is a right triangle
