Unit 3 Lesson 6 Right Triangles and Trgonometry Unit Test (part 1)   (100% I took the test)

1. B. Obtuse

2. C. 12 square root 2 ft

3. D. 9 square root 2 inches

4. B. 32.23

5. C. 63.26 degrees

6. C. 197.5 meters

7. A. 105 ft

8. A. 458 meters

9. D. 139 feet

10. D. 18+6 square root 3

11. c^2=v6^2+8^2

    c^2=v100 (square root of 100 equals 10)

     c=10

     Yes, it is a right angle according to the pythagorean theorem

12. senx=(7) / (9)

     x=ASIN ((7) /(9))

     x=51.05755873

     x=51 rounded to the nearest degree
