Question

25. The sides BC, CA and AB Of A ∆ABC
have been produced to D, E and F respectively, and forming Exterior angle
∆ACD, ∆BAE, and ∆CBF, than
∆ACD+∆BAE+∆CBF is equal to.
a) 240°,b)12300°,c)320°,d) 360°​

Answer 1

Answer:

OPTION (d) 360

Step-by-step explanation:

∠ACD=A+B

∠BAE=B+C

∠CBF=A+C

∠ACD+∠BAE+∠CBF=2A+2B+2C

2(A+B+C)=2*180

=360

OPTION(d)360
