to solve this question, we can use two methods
1. relate it with opposite angles and subtract the angles from 360
2. use angle on a straight line is equal to 180 degree
i'll use the second method simply because it's faster and saves time
[tex]\begin{gathered} 36^0+b^0=180^0 \\ \text{reason: angles on a straight line is equal to 180 degre}e \\ b=180-36 \\ b=144^0 \end{gathered}[/tex]
from the calculation above, the value of angle b is 144 degrees
