9 is 3% of what number? Which proportion matches this information?
dimulka [17.4K]

Answer:

B

Step-by-step explanation:

3% = 3/100

So we can eliminate the first answer.

The proportions have to match each other so the number nine should be above and thus the x has only the option of being under it.

As a result, we eliminate the third answer and remain with one reasonable answer

Please help,I need it for tomorrow​
Inga [223]

Answer:

<C=26

<B=48

<D=106

<F=42

Step-by-step explanation:

I labeled all the angles to help this make more sense :)

So first we find <C, which is supplementary to <E so just do 180-154=26

Next, we know that <F and <B are equal because they form corresponding angles.

Angles <C <D and <B form a triangle. The three angles of a triangle always equal 180. Now that we know angles <C and <B, we just do 180-26-48=106.

Lastly, to find angle A, we just take 180-106-48=42.

Hope this helps
