Answer:
x = 102 , y = 35
Step-by-step explanation:
x and 78 are same- side interior angles and sum to 180° , that is
x + 78 = 180 ( subtract 78 from both sides )
x = 102
x and 6y - 108 are vertically opposite angles and are congruent , so
6y - 108 = 102 ( add 108 to both sides )
6y = 210 ( divide both sides by 6 )
y = 35
