I think its correct but suggestions
didn't know the best format for this

Two things wrong.

First, the angle for the final leg. If the angle for the first leg is $0^\circ$, that means you are starting angle measurements from the eastward direction. So the angle for the third leg is $270^\circ - 53^\circ = 217^\circ$.

Second, for the $y$-component of the final leg you have repeated $C_x$ instead of calculating $C_y$.

ok i see the c_x error
but isn't due east mean heading east?

$\sqrt{(620+(220\sqrt{2})+(-264))^2+(0+(-220\sqrt{2})+(-264))^2}\approx881 \, km$

hopefully
