Iwill award brainliest! in the figure, a║b. find x+y in terms of z and w. a. 180°+z−w b. 180°–z−w c. w−z d. 180°+w−z

A. 180°+z−w

Step-by-step explanation:

We know that x  + w = 180  because they are same side exterior angles and a and b are parallel.

z=y  because they are alternate interior angles and a and b are parallel.

x  + w = 180

Solve for x by subtracting w from each side

x = 180-w

y =z

Lets find x+y

x+y

(180-w) +z

Rewriting

180+z-w

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
