Correct Answer: D. music

Correct Answer: C. 59.5°

Explanation

\(\overrightarrow{r} . \overrightarrow{t} = |\overrightarrow{r}||\overrightarrow{t}|\cos \theta\)

\(\overrightarrow{r} . \overrightarrow{t} = (3i + 4j) . (-5i + 12j) = -15 + 48 = 33\)

\(|\overrightarrow{r}| = \sqrt{3^{2} + 4^{2}} = \sqrt{25} = 5\)

\(|\overrightarrow{t}| = \sqrt{(-5)^{2} + 12^{2}| = \sqrt{169} = 13\)

\(\cos \theta = \frac{\overrightarrow{r} . \overrightarrow{t}}{|\overrightarrow{r}||\overrightarrow{t}|}\)

\(\cos \theta = \frac{33}{5 \times 13} = \frac{33}{65}\)

\(\theta = \cos^{-1} {\frac{33}{65}} \approxeq 59.5°\)

Correct Answer: B. personification

Explanation

The line 'The sun used to smile in my hut' is an example of 'Personification'. Personification is a figure of speech in which a thing, an idea or an animal is given human attributes.

The other options do not fit the context of the question. 'Rhetorical Question' is a question asked in order to create a dramatic effect or to make a point rather than to get an answer. 'Zeugma' is a figure of speech in which a word applies to two others in different senses. 'Apostrophe' is a figure of speech in which the speaker directly addresses an absent or imaginary person, or some abstraction.
