Question

In parallelogram RSTU if m, angle, U, R, S, equals, 10, degreesm∠URS=10
∘
find m, angle, T, U, Rm∠TUR.

Answer 1

In parallelogram RSTU the angle ∠URS is the angle at R, so m∠R = 10°. Consecutive angles in a parallelogram are supplementary, so the angle at U is 180° − 10° = 170°. Thus m∠TUR = 170°.
