Look at the bottom triangle which is a equilateral triangle as all angles are y degree.
Therefore \(y = 60\) as \(60*3 = 180\)
Looking at the straight angle with x and y we get x=120 because angles in a straight line add to \(180\) and \(y = 60\)
Therefore \(x*y = 120*60 = 7200\)
Therefore \(y = 60\) as \(60*3 = 180\)

the upper part is a hexagon (6-sided polygon), the sum of interrior angles of a hexagon is (6-2)*180=720, so x has a value of 720/6=120. at the bottom it is clear that x+y=180, then y=60 so 120*60=7200.
