The angle measures of quadrilateral RSTU are shown.m∠R = (2x)°m∠S = (3x – 35)°m∠T = (x + 35)°

Yes, opposite angles R and T are congruent to each other if x = 35.

Yes, consecutive angles R and S are congruent to each other if x = 35.

No, if x = 35, all three given angles measure 70°. The fourth angle would measure 150°.

No, if x = 35, the three given angle measures make it impossible for the figure to be a quadrilateral.

Circle B is shown. Line segments C B, D B, and E B are radii. Angle C B E is 52 degrees and angle E B D is 160 degrees.
