The angle measures of 8x and 12x are 72 and 108 degrees, respectively
How to determine the angle measures of 8x and 12x
From the question, we have the following parameters that can be used in our computation:
The parralel transversal model
The angles 8x and 12x are angles on a line
So, we have
8x + 12x = 180
This gives
20x = 180
x = 9
Using the above as a guide, we have the following:
8x = 8 * 9 = 72
12x = 12 * 9 = 108
Hence, the angle measures of 8x and 12x are 72 and 108 degrees, respectively
