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:

\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}

Here, we can say that AB = c = 38, C = 128, and AC = b = 10. Plug these in to find B:

\frac{b}{sinB} =\frac{c}{sinC}

\frac{10}{sinB} =\frac{38}{sin128}

Solve for B:

B ≈ 12.0°

12.

Use the Law of Sines as above.

\frac{a}{sinA} =\frac{b}{sinB}

\frac{23}{sinA} =\frac{28}{sin(43)}

Solve for A:

A ≈ 34.1°

9. Which point of view is most likely to be uni eliable in a story?
QveST [7]

This question includes some misspelled words; here is the correct question:

Which point of view is most likely to be unreliable in a story?

All points of view in a story are equally reliable.

The first person narrator is most likely to be unreliable.

All points of view in a story are equally unreliable.

The third-person point of view is most likely to be unreliable.

The correct answer is The first-person narrator is most likely to be unreliable.

Explanation:

In a narrative text, an unreliable narrator implies the narrator lies on purpose to the reader, or his/her version of the story is not completely accurate. This feature of narration occurs mainly if the story, novel, etc. includes a first-person narrator. This is because in a first-person narrator, the thoughts, feelings, and point of view of one of the characters prevail, and this causes the events told are subjective and therefore more likely to be inaccurate. Also, this does not occur if there is a third-person narrator because in this case the narrator acts as an observer and this makes it more objective.
