Answer:
x = 0.25 or
Step-by-step explanation:
2(2x + 3) - 2 = 5 (Given)
2 · 2x + 2 · 3 - 2 = 5 (Distributive Property of Equality)
4x + 6 - 2 = 5 (Simplify)
4x + 4 = 5 (Simplify)
4x + 4 - 4 = 5 - 4 (Subtraction Property of Equality)
4x = 1 (Simplify)
(Division Property of Equality)
x = 0.25 or (Simplify)
Answer:
10. Not enough information
11. B ≈ 12.0°
12. A ≈ 34.1°
Step-by-step explanation:

We need to use the Law of Sines, which states that for a triangle with lengths a, b, and c and angles A, B, and C:
Here, we can say that AB = c = 38, C = 128, and AC = b = 10. Plug these in to find B:
Solve for B:
B ≈ 12.0°
12.
Use the Law of Sines as above.
Solve for A:
A ≈ 34.1°
