In circle o, su is a diameter. circle o is shown. line segment s u is a diameter. line segments r o and t o are radii. points r and t are between points s and u. angles s o r and t o u are congruent. angle r o t is (13 x + 15) degrees and angle t o u is (9 x + 5) degrees. what is marc s t? 100° 108° 130° 160°

130°

Step-by-step explanation:

See the attached diagram.

Given that ∠ ROS = ∠ TOU = 9x + 5

Again, ∠ ROT = 13x + 15.

Therefore, 13x + 15 + 2 (9x + 5) = 180

⇒ 31x + 25 = 180

⇒ 31x = 155

⇒ x = 5

Hence, ∠ SOT = ∠ SOR + ∠ ROY = 9x + 5 + 13x + 15 = 22x + 20 = 130°
