Answer
Step-by-step explanation
Given the figure, we can deduce the following information:
a and b cut by transversal lines
To determine the value of x, we redraw the figure as shown below:
Since a and b are parallel lines, y must be equal to 36°. We also note that the angles on a straight add up to 180°. So,

Therefore, the equation that can be used to solve for x is:

Now, we get the value of x:

Therefore, the value of x is 79°.
