Answer:
x=45.5
Step-by-step explanation:
sum of angles of a quadrilateral is 360°
so 3x - 11+x+8+x-8+2x+7+x=360°
or 8x-4=360
or, x=364÷8
hence
x=45.5
I would say all you have to do is add those sides up then minus it with the total you’re trying to find
Step-by-step explanation:
the angles are supplementary to the angle in the diagram is Angle BCF
