Question

the measure of one angle of a parallelogram is 70°.Find the other measures of remaining angles

Answer 1

the angle opposite to 70 degree = 180-70=110 (because sum of opposite angles of a parallelogram is 180)
since opp sides are parallel, it will be a pair of co-interior angles, therefore angle adjacent to 110 will be 70 and angle adjacent to 70 will be 110.

hope it is helpful.. draw the figure and then try to substitute the values. 

Answer 2

One angle is 70°
Lets consider a parallelogram ABCD
<A =70° {given}
<B =180-70= 110° {adjacent angles are supplementary (<A+<B=180°) }
<C =70° {Opposite angles of a parallelogram are same (<A=<C) }
<D =110 {Opposite angles of a parallelogram are same (<B=<D) }

<A=70°
<B=110°
<C=70°
<D=110°
