if i’m not wrong the shape is trapezium, the side should be the same which mean it’ll be 65 ay the y side and 125 at x side. so we all can see the first triangle is 90 which we can get x with 125-90=35 so the answer for x=35 then to find x we just need minus the whole sec triangle which is 180-125-35=20 so y=20
hope you understand what i’m trying ti explain for you
