The flattened corner is divided into n equal corners. find the degree measure from these angles if n = 18.

As you know, the degree measure of the unfolded angle is 180˚. By the condition of the problem, the extended angle was divided into n equal angles, so the degree measure of one of them will be equal to 180˚: n. Substitute the value given in the condition:

if n = 18, then 180˚: n = 180˚: 18 = 10˚. That is, the degree measure of the desired angle is 10˚.

Answer: The degree measure of the angle is 10˚.
