# One of the two vertical angles is 71 degrees. How many degrees is the other angle?

| Vertical angles are two angles formed by the intersection of two straight lines, with the extension of the side of one corner being the side of the other corner. It is known that the vertical angles are equal. This means that the other vertical angle is equal to this angle (71 degrees). This means that you can find an angle that is adjacent to a given angle. The sum of adjacent angles is always 180 °. So, to find another adjacent angle, you need to subtract the given angle from 180 degrees, which is adjacent to the given one.

Adjacent angle = 180 – 71 = 109 °.

Answer: vertical = 71 °, adjacent = 109 °.
