Question

solve these questions in step by step

Answer 1

(iii) ∠BOC = 180°- ∠AOC    ( linear pair)
           = 180°-50°
           = 130°
(ii)∠ AOD = 180° - ∠AOC
               = 180° -50°
               =130°
(i) ∠BOD= 50° (OPPOSITE ANGLES)


I guess its like this.... hope it helps...:)

Answer 2

<BOD=50°(opposite angles)
<AOD=130°(linear pair)[180°-50°]
<BOC=130°=AOD(linear pair)
