Question

The sides BC,CA and AB of triangle ABC have been produced to D , E and F respectively. find angle BAE+CBF + ACD

Answer 1

hope this helps you....

Answer 2

hey
____

x + y+ z = 180 (angle sum property of a triangle )

x + <3 = 180

y + <1 = 180

z +<2 = 180

by linear pair

now adding eqn (1), (2),(3)

(x + y + z )+ ( <1 + <2 + <3) = 540

<CBF + <ACD + < BAE = 540 - 180 = 360

hope helped
