Laws of Sines with find the angle. Find each measurement indicated. Round your answers to the nearest tenth. Part 4

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°

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

ask the math teacher she or he would know lol.
