Answer:
∠R= 110°, ∠U= 70°, ∠T= 110°
Step-by-step explanation:
Since, RSTU is a parallelogram, therefore using the properties of parallelogram, ∠S=∠U= 70° ( Opposite angles of parallelogram are equal).
Using the property, sum of adjacent angles is equal to 180°, therefore,
⇒∠S+∠R= 180°
⇒70°+∠R= 180°
⇒∠R= 180°- 70°
⇒∠R=110°
Also, ∠R= ∠T= 110° (Opposite angles of parallelogram are equal).
Thus, ∠R=110°, ∠T= 110° and ∠U=70°
