Answer:
The measure of x and y are 45° and 45° respectively.
Explanation:
From the figure, it can be seen that the line l is parallel to line m, and x is the angle made between the horizontal axis and the vertical axis, therefore the measure of the angle x will be 90°.
Using the straight line property, we get

Substituting the value of x in the above equation , we get



Therefore, the measure of x and y are 45° and 45° respectively.
