Question

anyone solve this problem with explanation.

Answer 1

Answer:

here's your answer ^ω^.....have a great day ahead ✌

Step-by-step explanation:

11. 3x+42=180° (linear pair)

3x=180-42

3x=138

x=138/3

x=46

12. 2x+15=3x-40. (alternate interior angles)

15+40=3x-2x

55=x

Answer 2

Answer:

11.  x=46°

12. x=55°

Step-by-step explanation:

11.

   AS 3x AND 42° ARE IN LINEAR PAIR

   SO,

    3x+42°=180°

    3x=180°-42°

    3x=138°

    x=138°/3

   x=46°

12.

   AS,

    (2x+15) AND (3x-40) ARE ALTERNATE INTERIOR ANGLES,

    SO,

    (2x+15)=(3x-40)

    15+40=3x-2x

    55°=x

I HOPE YOU UNDERSTOOD THE QUESTION!!!
