Question

The adjacent angles of a parallelogram are (2x-4)° and (3x-4)°. Find the measures of all angles of the parallelogram.

Answer 1

Sum of adjacent angles of a parallelogram is 180 °.

So.(2x-4)+ (3x-4) = 180.

5x-8 =180.

5x= 188.

x= 37.6°

So. Two pairs of opposite angle each : 71.2°

Another pairs of opposite angle each : 108.8 °.
