A pet rescue center takes in animals from a local shelter. Half of the animals that they take in are cats. Let a = the total number of animals. Let c = the number of cats. Complete the table to show the number of cats, c, that are taken in by the pet rescue when a animals are taken in.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

60: 45 =12: 9 =4: 3 so the answer is 4: 3
