In the given figure, two rays BD and CE intersect at a point A. The side BC of ∆ABC have been produced on both sides to points F and G respectively. If ∠ABF = x°, ∠ACG = y° and ∠DAE = z° then z = ?(a) x + y – 180(b) x + y + 180(c) 180 – (x + y)(d) x + y + 360°

Answer» In the given figure, two rays BD and CE intersect at a point A. The side BC of ∆ABC have been produced on both sides to points F and G respectively. If ∠ABF = x°, ∠ACG = y° and ∠DAE = z° then z = ?

(a) x + y – 180

(b) x + y + 180

(c) 180 – (x + y)

(d) x + y + 360°
