If x and y are the lengths of two sides of a triangle such that the product xy = 18, where x and y are integers, then how many such triangles are possible?
If x, y, z are 3 non zero positive integers such that x+y+z = 8 and xy+yz+zx = 20, then What would be minimum possible value of x*y^2*z^2
If in a right angle triangle the lengths of the two sides including the right angle are 27 and 120 units long, how many units is the third side?
