Question

I just need the answer to number 2

Answer 1

∠ A'OB' = 79°

Explanation:

∠ AOC = ∠ C'OA' = 35° ( vertical angles )

BOB' is a straight angle , thus

∠ COB' = 180° - (79 + 35)° = 180° - 114° = 66°

C'OC is a straight angle, thus

∠ A'OB' = 180° - (66 + 35)° = 180° - 101° = 79°

Answer 2

79°

( vertically opposite angles are equal. So, <AOB = < A'OB' )
