The values of x and y are 4 and 3 respectively.
From the diagram ;
11x + 34 = 15x + 18
11x - 15x = 18 - 34
-4x = -16
x = 4
To find y :
11(4) + 34
44 + 34
= 78
The sum of angles on a straight line ;
90 + 78 + 5y - 3 = 180 (sum of angles on a straight line)
165 + 5y = 180
5y = 180 - 165
5y = 15
y = 3
Hence, the values of x and y are 4 and 3 respectively.
