B. 90
Because, a circle is 360 degrees total. Angle FG is 130 degrees. Angle GD is 90 degrees. It's remaining 2 so.... 130+90=220 But every circle is 360 degrees so... 360-220=140. And ED looks similar to GD which is 90 degrees
I think the slope of L'M' is still 1.75 and it still passes through point C.
I think I know this but I need a picture of it
