The sides BC, BA and CA of ΔABC have been produced to D, E and F respectively, as shown in the given figure. Then, B = ?


A. 35o

B. 55o

C. 65o

D. 75o

Answer :

BAC = 35o (opposite pair of angles)


BCD = 180 – 110 = 70o (linear pair of angles)


Now, in Triangle ABC we have,


A + B + C = 180o


35 + B + 70 = 180


B = 180 – 105 = 75o
