Answer:

$\frac{1}{5} ;\frac{2}{10} ;\frac{3}{15}$

Step-by-step explanation:

To find the three ratios we only have to find the most simple ratio of $\frac{7}{35}$ , and then find the other ratios that are equal to it.

So, $\frac{7}{35} = \frac{1}{5}$

Also, $\frac{1}{5} =\frac{2}{10}$ , by multiplying by two each part of the fraction.

Similarly, $\frac{3}{15} = \frac{1}{5}$ , by multiplying by three.

Therefore, comparing all these ratios, all are the same, they are equal to $\frac{1}{5}$ . So, the option that correctly has these choices is D.

A) Two angles are adjacent if their measures add up to 90°.

Answer:

A) False

B) False

Step-by-step explanation:

A. Two angles whose measures add up to 90° are said to be complementary, while two angles are adjacent when formed beside each other. So, adjacent angles might be complementary or supplementary. Thus, the answer to the first part of the question is false.

B. When two angles share a side, they are said to be adjacent to each other. But supplementary angles add up to $180^{o}$ . Since adjacent angles might be complementary or supplementary, then the answer to the second part of the question is false.
