Sam is 36. he is 3 times as old as tracey’s and dan’s ages combined. tracey is 5. if d represents dan’s age, which equation could be used to find dan’s age?

36 divided by 3 =12. 12-5 =d. So Dan is 7 years old

well what did you do it matters what you did : )

step-by-step explanation:

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.
