$\frac{1}{2} x=a=\frac{2}{3} y\\\frac{1}{2}x=a\\x=2a \\\frac{2}{3} y=a\\y=\frac{3}{2} a\\x+y=2a+\frac{3}{2} a=\frac{4a+3a}{2} =\frac{7}{2} a=na\\n=\frac{7}{2}$

An outside angle is equal to the sun of the two opposite inside angles.

The given inside angle is 75, the angle next to it is also 75 ( because there is a single line through the red arc, this means the angles are identical).

W = 75 + 75

W = 150 degrees.
