1.	the ratio od adjacent angles of a parallelogram is 4x5 find all the angles of the parallelogram....pls tell fast urgent !!
Answer» Answer: let the ANGLES be 4X and 5x since adjacent angles in a PARALLELOGRAM are co-interior therefore 4x + 5x = 180 9x = 180 x = 180/9 = 20 angles = 4x=80 and 5x=100 since opposite angles of a parallelogram are EQUAL therefore all the angles are:- 80, 100, 80, 100

Answer»

Answer:

let the ANGLES be 4X and 5x

since adjacent angles in a PARALLELOGRAM are co-interior

therefore 4x + 5x = 180

9x = 180

x = 180/9 = 20

angles = 4x=80 and 5x=100

since opposite angles of a parallelogram are EQUAL

therefore all the angles are:- 80, 100, 80, 100
