Hope this helps. Your diagram seems to have most of the sides. Probably just missing the cosine rule

Hi can you tell me how to find GX?
Hi Annela! GX can be found by considering right-angled triangle CXG (though we can't view it clearly from this view, so we must draw out the triangle ourselves or imagine the view from the right side of the cuboid) where the right angle is at C.
So,
(GX)^2
= (CX)^2 + (CG)^2
= 80 + (7^2)
= 129
So,
(GX)^2
= (CX)^2 + (CG)^2
= 80 + (7^2)
= 129
