The calculated values of x and y are x = 15 and y = 2.4
How to determine the values of x and y
From the question, we have the following parameters that can be used in our computation:
The triangle
The sum of angles on a straight line is 180 degrees
So, we have
8x + 60 = 180
The 60 is gotten from the equilateral triangle in the figure
So, we have
8x = 120
Evaluate
x = 120/8
x = 15
Next, we have
2(5y + 1) = 26
5y + 1 = 13
y = 2.4
Hence, the values of x and y are x = 22.5 and y = 5
