Question

find each angle of a parallelogram if two consecutive angles are in the ratio 1:3.

Answer 1

Answer:

some of adjacent angles of parallelogram is 180 degree. .

so.. let no. x

x +3x =180

4x =180

x=180/4

45degree

so.. one angle is 45...other one is 3*45=135

and the opposite angles of parallelogram are equal

so.. angle opposite to 45 will be of 45 degree.. and opposite to 135 will be of 135 degree
