Answer:
2.04
Step-by-step explanation:
The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h.
<span>A=<span><span>(<span>a+b</span>)</span>2</span>h</span>
Solve for a.
Answer: 
radians
<u>Explanation:</u>
csc⁻¹ (csc -315°)
csc⁻¹ and csc cancel out so you are left with -315°
-315° + 360° = 45°
Look at the Unit Circle to see that 45° = radians
1. x = z/y 10. a = 2s - b - c
2. d = St 11. m = p/n
3. n = N/r 12. f = 2jg
4. T = C/R 13. b = -a + 2c
5. m = Ln 14. q = 4p/r
6. u = v - at 15. C = -L + 2a + 3b
7. p = r/q 16. a = 4d - 2b - 3c
8. y = X - 2z 17. c = b^2 - a^2
9. b = 3c - 2a
18. r = -p^2 + q^2 + 3
19. r = t - 2s
phew, that was a lot. i hope this helps you and that you get a good grade!!
