Answer:
x = 21
y = 114
Step-by-step explanation:
From the picture attached,
Lines 'm' and 'l' are the parallel lines and a transversal line is intersecting this line.
Therefore, (3x - 15)° + (6x + 6)° = 180° [Sum of consecutive interior angles is 180°]
9x - 9 = 180°
9x = 189
x = 21
(y + 18)° = (6x + 6)° [Alternate interior angles are equal in measure]
y = 6x + 6 - 18
y = 6x - 12
y = 6(21) - 12
y = 126 - 12
y = 114
