Let x = first number and y = second number.
The first statement is expressed as x*y = 713 The second statement is expressed as x = y + 9 To find x, use the second equation in terms of y, that is y = x - 9. Then substituting it to the first equation yields x*(x - 9) = 713
Since the triangle has equal sides it will carry onto it self at 120, since it can rotate 360 grades only and it has 3 sides so it will rotate in one third of 360 so 120
