Answer:
Option b) x = 15, y = 17
Step-by-step explanation:
In this picture the two lines are intersecting each other at point. Measurement of one angle is 112° and opposite angle of 112° is (7x+7)
Since we know opposite angles are always equal
Therefore 112 = 7x + 7
7x = 112 - 7 = 105
7x = 105
x = 105/7 = 15
Since (7x + 7) + 4y = 180° (sum of all angles on a line is 180°)
7×15 + 7 + 4y = 180
105 + 7 + 4y = 180
4y = 180 - 112= 68
y = 68/4 = 17
Therefore Option b is the right option.
