$1620°$

Three of the exterior angles of a hexagon are $40°, 52°$and $85°$ respectively and each of the remaining exterior angle is $x°$, calculate $x$.

The sum of interior angles of a polygon is $6$ times the sum of its exterior angles. Find the number of sides of the polygon.

The difference between an exterior angle of a regular polygon of $\text{'}n\text{'}$ sides and an exterior angle of a regular polygon of $\text{'}(n+1)\text{'}$ sides is equal to $5°$; find the value of $\text{'}n\text{'}$

The angles of a Pentagon are $(3x+4)°,(x+20)°,(3x-5)°+(2x+10)° and (4x-9)°,$if $x=k°$ then find $k$.
