Step 1
If one angle measures 60 degrees, then the opposite angle in the parallelogram will also measure 60 degrees. This is because opposite angles in a parallelogram are congruent. b. If one angle measures 68 degrees, then the opposite angle in the parallelogram will Show more…

For a quadrilateral $A B C D,$ the measures of its angles are $\mathrm{m} \angle A=x+16, \mathrm{m} \angle B=2(x+1), \mathrm{m} \angle C=\frac{3}{2} x-11$ and $\mathrm{m} \angle D=\frac{7}{3} x-16 .$ Determine the measure of each angle of $A B C D$ and whether $A B C D$ is a parallelogram.
