Answer by greenestamps(13198) (Show Source): You can put this solution on YOUR website!

(1) Angle ABF is 90 degrees.
(2) Angle ABC is 108 degrees.
(3) You can find the measure of angle CBF knowing that angles ABF, ABC, and CBF sum to 360 degrees.
(4) The square and pentagon have the same side length, so triangle CBF is isosceles. Knowing the measure of angle CBF lets you determine the measure of angle BCF.
