Answer:
10. Not enough information
11. B ≈ 12.0°
12. A ≈ 34.1°
Step-by-step explanation:
10. Not enough information
11.
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°
Answer:
23:25

Hello there,
Well to find the total time you would have to set up a proportion...
6 / 3/5 = x / 1
Now you crosss multiply and divide...
6 * 1 = 6
6 / 3/5 =30/3 = 10
Answer: 10 hours
Hope I helped!!

Here, I think I can help you out:
1. 21 ÷ 3
= 7
Therefore, the length is 7cm².
2. 35 ÷ 7
= 5cm²
- And so on. Simply divide the area by the length of the side given; you can answer up to question six using this strategy.
7. All sides of a square are the same length.
7 x 7
= 49cm²
9. 2 x 3.5
= 7m²
- The formula to find the area of a square/rectangle is length x width. Just multiply the given lengths for the answers :)
Answer:
There's no equation. You must've forgotten to put the file in the question.
