Two regular polygons are such that the ratio of the measures their interior angles is 4 : 3 and the ratio between their number of sides is 2 : 1. Find the number of sides of each polygon.
In the following figure, both RISK and CLUE are parallelogram. Find the value of x.
RISK is a parallelogram.
∴ (∵ Adjacent angles of parallelogram are supplementary)
or
Two opposite angles of a parallelogram are (5x - 8)° and (2x + 82)°. Find the measures of each angle of the parallelogram.
In a parallelogram if measures of two adjacent angles are in the ratio of 4 : 5, find all the angles.
