Inscribed Angles

Skill Practice!

In ⊙S, mKL = 80, mLM = 100, and mMN = 60. Find the measure of each angle.

1. m∠1 2. m∠2

3. m∠3 4. m∠4

5. m∠5 6. m∠6

ALGEBRA Find the measure of each numbered angle for each figure.

7. m∠1 = 5x – 2, m∠2 = 2x + 8 8. m∠1 = 5x, m∠3 = 3x + 10,
m∠4 = y + 7, m∠6 = 3y + 11.

Quadrilateral RSTU is inscribed in ⊙P such that mSTU = 220 and m∠S = 95. Find each measure.

9. m∠R 10. m∠T

11. m∠U 12. mSRU

13. mRUT 14. mRST
