Answer:
x = 15, y = 21
Step-by-step explanation:
We have 2 vertical angles that are equal to each other, and equals (6x - 11).
For right triangle:
(6x - 11) + 81 + (x+ 5) = 180
6x - 11 + 81 + x+ 5 = 180
7x + 75 = 180
7x = 105
x = 15
For left triangle:
(4y - 18) + (6x - 11) + (y +14) = 180
4y - 18 + 6x - 11 + y +14 = 180
5y + 6x - 15 = 180
Substitute x = 15.
5y + 6*15 - 15 = 180
5y + 75 = 180
5y = 105
y = 21
