Answer:

100º

Explanation:

Since these angles are on a single straight line, both of their measures should add up to 180º.

180º - 80º = 100º

Hence the measure of the unknown angle is 100º.

Answer: n = 100°

Explanation:

These two angles are supplementary angles. This means that when added togther, they will be equal to 180 degrees. With this information, we can subtract 80 degrees from 180° to find n.

n = 180° - 80°

n = 100°
