Parallelogram R S T U is shown. Angle S is 70 degrees.
What are the missing angle measures in parallelogram RSTU?

m∠R = 70°, m∠T = 110°, m∠U = 110°
m∠R = 110°, m∠T = 110°, m∠U = 70°
m∠R = 110°, m∠T = 70°, m∠U = 110°
m∠R = 70°, m∠T = 110°, m∠U = 70°

In a parallelogram opposite angles are equal and adjacent angles are supplementary. Since ∠S = 70°, its opposite ∠U = 70°, and the adjacent angles ∠R and ∠T are 180° − 70° = 110°.

So m∠R = 110°, m∠T = 110°, m∠U = 70°.
