A pentagon has interior angles of 80,90 and 125 degrees. Each of the remaining angles is equal to x degree.
Calculate the value of x.
---------
Note: A pentagon has 3(180) = 540 degre in the interior.
-------
(80+90+125+2x) = 540
295 + 2x = 540
----
2x = 245
-----
x = 122.5 degrees (Measure of each of the remaining angles)
-----------
