Answer:

Find length opposite to 30deg

Opposite = tan(30)*42

= 24.2

Whole side = 24.2+10

Find angle of 0 + 30deg: (say x)

Tan(x) = 33.2/42

Arctan(0.79) = x

x = 38.3

The angle to find:

38.3-30:

8.3

The angle is 8.3deg.

The results of an election are shown in the table below.

vazorg [7]

We are given the results of an election:

Candidate Fraction of votes

Johnson = $\frac{1}{9}$

Smith = $\frac{7}{18}$

Dragovic = $\frac{1}{2}$

Now, we need to find the difference between the fractions of votes received by Dragovic and Johnson.

Therefore, difference is :

$\frac{1}{2} - \frac{1}{9}$

Taking common denominator of 2 and 9 is 18.

$=\frac{1\times9}{2\times 9} - \frac{1\times 2}{9\times 2}$

$=\frac{9}{18} - \frac{2}{18}$

$=\frac{9-2}{18}$

$=\frac{7}{18}$

Therefore, the difference between the fractions of votes received by Dragovic and Johnson is $\frac{7}{18}$ .
