two opposite angle of a parallelogram are(5x-20) and (70-4x) what are the measurements of other angle of parallelogram

Answer 1

The others are

180-(5x-20) = 200-5x
or
180-(70-4x) = 110+4x

In either case, opposite angles are equal, so if you want the actual numeric measure, just set the two expressions equal, solve for x, and the evaluate the expressions.

Answer 2

80 ,048
