Question

Find the measure of the four angles of a parallelogram whose causes cutive angles are in the ratio 1:3.

Answer 1

let consecutive angles= 1x or x, and 3x...in a parallelogram. consecutive angles are supplementary..:. x+3x=180....=4x=180....x=180/4...x=45angles =x=45.. and 3x=3*45=135..and opp sides of parallelogram are equal :. other two angles are 45 and 135..so all the angles are 45..135..45..135...
