Question
(a)The sizes of the six interior angles of a hexagon are
x°, (x + 10)°, (x + 20)°, (2x − 30)°, (2x − 10)° and (x + 50)°.
Form an equation in x, solve it, and hence find the size of the largest interior angle of the hexagon.
(b)A different polygon is regular and each of its interior angles is 156°. Work out the number of sides of this polygon.
