Stuck again lol.

A, B, C & D form the vertices of a quadrilateral.
A, B & F lie on a straight line.
C, B & E lie on a straight line.
Find the value of the angle x.

IDK, if this is correct.. 180-107=73 degrees. We have 71 degrees, 61 degrees, 90 degrees, and x degrees.

So, 71+61+90+x=360, 222+x=360, x=138 degrees.
