Answer:
Step-by-step explanation:
You want the values of x and y when corresponding angles at parallel lines are marked (9x -14)° and (7x +18)°, and a vertical angle to those is marked y°.
Corresponding angles
Corresponding angles where a transversal crosses parallel lines are congruent:
(9x -14)° = (7x +18)°
2x = 32 . . . . . . . . . . divide by °, add 14-7x
x = 16
Then these angles are ...
(9(16) -14)° = (144 -14)° = 130°
Vertical angles
Vertical angles are congruent, so ...
y° = 130°
y = 130
