#color(blue)(108^@#

Explanation:

The sum of the interior angles of a regular polygon is given by:

#180^@n-360^@#

Where #bbn# is the number of sides:

A pentagon has 5 sides, so:

#180^@(5)-360^@=540^@#

Since we have 5 sides we also have 5 interior angles. One interior angle is therefore:

#(540^@)/5=108^@#
