Answer 1

Explanation:

Consider ∠AOC as 5x and ∠AOD as 7x From the figure we know that ∠AOC and ∠AOD for linear pair of angles So it can be written as ∠AOC + ∠AOD = 180o By substituting the values 5x + 7x = 180o On further calculation 12x = 180o By division x = 180/12 x = 15o By substituting the value of x ∠AOC = 5x So we get ∠AOC = 5 (15o) = 75o ∠AOD = 7x So we get ∠AOD = 7 (15o) = 105o From the figure we know that ∠AOC and ∠BOD are vertical angles So we get ∠AOC = ∠BOD = 75o From the figure we know that ∠AOD and ∠BOC are vertical angles
