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.
Looks good to me Tertre
