Question

I'm looking for the answer to angle b if 36° is the other angle

Answer 1

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

`\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}`

from the calculation above, the value of angle b is 144 degrees
