Question

sum of a pair of opposite angles of a parellogram is 240 . find the angles of parellogram ​

Answer 1

Step-by-step explanation:

We know that the sum of the opposite angles of parallelogram are equal. ... Then, x + x = 240 => 2x = 240 => x = 240/2 => x = 120 Other opposite angles = 180° - 120° = 60° Hence , the angles of the parallelogram are 120° , 60° , 120° and 60°.
