Let's Analyze (Enrichment Exercises) Use the law of tangents to find the measures of the unknown angles of AABC. Then use the law of sines to the find the length of the unknown side. Express angle measures to the nearest degree and lengths to two significant digits. 6. ZA = 47°, ZB = 29°, a + b = 49 7. ZA = 37°, ZB = 62°, a + b = 76 8. ZA = 94°, 2C = 22°, a + b = 114 9. ZA = 42°, 2C = 101°, a + b = 213 10. ZA = 48°, ZB = 60°, a + b = 86
