The sides are in the ratio 1 : 1 : sqrt2 where sqrt 2 = hypotenuse

so if the length of one of the legs is 2 cm the hypotenuse will be of length 2 *sqrt 2 cms.

b ) sin 45 = 1 / sqrt2 = sqrt2 / 2

c) if the 2 legs of triangle are both 2 cms area will be 1/2* 2* 2

Given parameters:

Cost price of the article = Nu.28.30

Selling price of the article = Nu.29.30

Unknown:

Gain percentage = ?

The gain percentage is the same as the percentage profit on a trade.

The formula is given as:

Gain percentage = $\frac{Profit}{Cost price} x 100$

Profit = Selling price - Cost price

= Nu.29.30 - Nu.28.30

= Nu. 1

Now input the parameters and solve;

Gain percentage = $\frac{1}{28.3} x 100$

= 3.5%

The gain percent is 3.5%
