Question

if one angle of a parallelogram is of measure 70. Find the measure of the remaining angles of the parallelogram.

Answer 1

Angle opposite to 70 is 70 degree itself. Angle adjacent to 70 is 110. And the last angle opposite to 110 is 110 itself.

Answer 2

the angles of a parallelogram add up to 360°

the opposite angles are equal

therefore, x+x+70+70=360

=2x+140=360

=2x=360-140=220

=x=$\frac{220}{2}$

=x= 110

therefore, the angles are 70, 70, 110 and 110
