Question

Do the answer fast plz​

Answer 1

Answer:

x = 67

Step-by-step explanation:

56 + x = 123 ( Sum of interior angles is equal to exterior angle )

x = 123 - 56

x = 67

OR

1.∠ACB + 123 = 180     ( Linear Pair )

           ∠ACB = 180 - 123

                      = 57

2. x + 56 + ∠ACB  = 180    ( Angle Sum Property )

          x + 56 + 57 = 180

                           x = 180 - ( 56 + 57 )

                           x = 67
