Question

if one angle of a parallelogram is 69 degrees,then find its other three angles

Answer 1

I well there are 4 angles in a parallelogram and 2 pairs with the same measure. So 2 of them are 69 degrees. Since the angles are supplementary in order to find the other ones simply do 180-69=a. So your answer will be 69, 69, a, a.
