Answer:
Step-by-step explanation:
The easiest way to do this is to solve for x. Since x and y are vertically opposite, y = x
40 + 50 + x = 180 degrees. A straight line has an angle of 180 degrees.
90 + x = 180 Subtract 90 from both sides
x = 180 - 90
x = 90
But y = x
so y = 90 degrees.
Thank you for the very clear explanation of what is happening in this question.
