180 × 3
=540

Fifth angle
=540-(100+175+85+75)
=540-435
=105

The sum of the interior angles of any polygon is
180(n-2)
where, n is the no. of sides of the polygon
Pentagon is a polygon with 5 sides... so,
180(n-2)
=180(5-2)
=180*3
=540 degrees
so the sum of the interior angles of the Pentagon is 540 degrees
Let the unknown angle be x
=100+175+85+75+x=540
435+x=540
x=105 degree
HOPE THE ANSWER IS CORRECT
