Question

plss guys give me a answer in method​

Answer 1

Step-by-step explanation:

1. solution,

    x + 145° = 180° [∵ being co-interior angle]

or, x = 180°-145°

∴ x = 35°

2. solution,

   ∴ x = 50° [ ∵ being alternate angle]

3. solution,

     x + 89° = 180° [∵ being co-interior angles]

or, x = 180° - 89°

∴ x = 91°

4. solution,

  x + 62° = 180° [∵ being co-interior angles]

or, x = 180° - 62°

∴ x = 118°

5. solution,

   x + 138° = 180° [∵ being co-interior angle]

or, x = 180° - 138°

∴ x = 42°

6. solution,

  ∴ x =  104° [∵ being alternate angle]

7 . solution,

  x + 68° = 180° [∵ being co-interior angle]

or, x = 180° -  68°

∴ x = 112°

8. solution,

  ∴ x = 130° [∵ being alternate angle]

9. solution,

 ∴ x =40°  [∵ being alternate angle]
