Answer:

25

Step-by-step explanation:

We can calculate for a using sine rule.

For angle A,

A + 27° + 82° = 180 ( sum of angles in a triangle).

A + 109 = 180

A = 180 - 109 = 71°

Therefore,

A = 71°

calculating for side a

\frac{sin \: 27}{12}  =   \frac{sin71}{a}  \\ a =  \frac{12 \times sin71}{sin27}  \\ a \:  =  \frac{11.346}{0.454}  \\ a = 25

Answer:

-46.91%

Step-by-step explanation:

Given:

Cost of buying the shares = $53,500

Selling cost of the shares = $3,300

Number of years = 2

Since the selling cost is less than the buying cost, therefore the statement for the loss can be verified

Now,

The loss = Selling cost - cost of buying = $3,300 - $53,500 = - $50,200

thus, the loss per year = \frac{\textup{50,200}}{\textup{2}} = -$25100

Hence,

Rate of return = \frac{\textup{Loss per year}}{\textup{Cost of buying}}\times100

or

Rate of return = \frac{\textup{-25100}}{\textup{53,500}}\times100

or

Rate of return = -46.91%
