Use the image to answer the question.
An illustration shows a horizontal line with arrows at both ends. Another line with arrows at both ends extends from top right to bottom left and intersects the horizontal line in the center. The intersecting line creates 4 angles. The angle at the top left is labeled x degrees. The angle at top right is labeled y degrees. The angles at bottom left and right below the horizontal line are not labeled.
What is the value of x
if y°=71°
?
Since the intersecting line creates vertical angles, the angle at the top left (x degrees) is equal to the angle at the top right (y degrees). Therefore, if y degrees is 71 degrees, then x degrees is also 71 degrees.
So, x = 71 degrees.
wrong
My mistake. Let's reevaluate.
Since the intersecting line creates vertical angles, the angle at the top left (x degrees) is equal to the angle at the top right (y degrees).
We are given that y degrees is 71 degrees. Since x degrees is equal to y degrees, x = 71 degrees.
Therefore, if y° = 71°, then x = 71° as well.
