The sale is 33% off notebooks. This can be found by first subtracting .8 from 1.2

1.2-.8=.4    Now divide .4 by 1.2 to get your answer.

\frac{.4}{1.2}=.33

.33=33%

You can also solve this mentally because if you know your basic multiplication tables, 3*4=12 and so \frac{2}{3} of 12 would equal 8.

Does you understand it now?

In the question it is already given that the actual cost of each notebook is $1.20. For the weekend, the notebooks would sold at a discounted rate of $0.80
he
The amount of discount during the weekend = (1.20 - 0.80) dollars
                                                                       = 0.40 dollars
So the amount of discount given during the weekend is $0.40
Now we need to find the percentage of discount given during the weekend.
Then
Percentage of discount during the weekend = (0.40/1.20) * 100
                                                                       = 0.33 * 100
                                                                       = 33
Then the percentage of discount given is 33%.

Step-by-step explanation:

Let alpha be the unknown angle. We can set up our sine law as follows:

\frac{ \sin( \alpha ) }{5 \: m}  =  \frac{ \sin(42) }{3.6 \: m }

or

\sin( \alpha )  =  \frac{5 \: m}{3.6 \: m} \times  \sin(42)  = 0.929

Solving for alpha,

\alpha  = arcsin(0.929) = 68 \: degrees
