Find the number of sides in a polygon if the sum of its interior angles is $1620°$.

Find the number of sides in a polygon if the sum of its interior angles is $16$ right angle.

If all the angle of hexagon are equal. The measure of each angle is $k°$, then find the value of $k$.

If the sum of exterior angles obtained producing in order the sides of polygon with $7$ sides is $k°$, then find the value of $k$.

If the sum of exterior angles obtained producing in order the sides of polygon with $10$ sides is $k°$, then find the value of $k$.

Two angles of a polygon are right angles and the remaining are $120°$ each. Find the number of sides in it.

The angles of a hexagon are $x+10° , 2x+20° ,2x-20° ,3x-50° ,x+40° and x+20° ,$ find $x$ in degrees.

 In a pentagon, two angles are $40°and 60°,$ and the rest are in the ratio $1:3:7$, find the biggest angle of the pentagon.
