Solve for x and y using the given angles

11. x=110 y=110

12. x=115 y=115

13. x=90 y=90

14. x=80 y=80

15. x=60 y=60

16. x=50 y=50

17. x=45

18. x=20

19. x=40

Step-by-step explanation:

11. Supplementary angles add up to 180. x is the supplement to the angle labeled 70. 180-70=110, so x=110. y is a corresponding angle to x, which means they are congruent, so y=110.

12. Vertical angles are congruent. x is the vertical angle to the angle labled 115, so x=115. y is a corresponding angle to x, which means they are congruent, so y=115.

13. The square means that the labeled angle measures 90 degrees. x is a corresponding angle to the labeled angle, making them congruent, so x=90. y is supplementary to x, meaning that the measures of both angles add up to 180. 180-90=90, so y=90.

14. The angle labeled 100 and y are supplementary angles, so they add up to 180. 180-100=80, so y=80. y and x are alternate interior angles, so they are congruent. This means that x=80.

15. The angle labeled 120 and x are consecutive interior angles, meaning they are supplementary and add up to 180. 180-120=60, so x=60. x and y are vertical angles, which are congruent, so y=60.

16. The angle labeled 130 and x are consecutive interior angles, meaning they are supplementary and add up to 180. 180-130=50, so x=50. x and y are alternate exterior angles, which are congruent, so y=50.

17. The angles labeled (2x-10) and 80 are alternate interior angles, meaning they are congruent. This means we can set up the equation 2x-10=80 to find the value of x. When solved, x=45. You can plug the value of x back in to check.

18. The angles labeled 120 and 3x are consecutive interior angles, so they are supplementary. This means we can set up the equation 120+3x=180 to find the value of x. When solved, x=20. You can plug the value of x back in to check.

19. The angles labeled 135 and (3x+15) are corresponding angles, so they are congruent. This means we can set up the equation 135=3x+15 to find the value of x. When solved, x=40. You can plug the value of x back in to check.
