Hello from MrBillDoesMath!

Answer:

BC = 3 * sin (66)/ sin(38)

Discussion:

From the law of sines:

sin(38) /3 = sin(66)/ BC

BC *  (  sin(38)/3 )  = sin(66)        => multiply both sides by BC

BC = sin(66) /  ( sin(38)/3)           => multiply both sides by ( 3/sin(38) )

BC = 3 * sin (66)/ sin(38)

which is the first choice.

Regards,  

MrB

P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!

Answer:

As there is one math problem over there.

Lets see the question first:

It says that "A hair dryer is rated 1200\ W,if you use the dryer for 0.25\ h.How much electric energy do you use ?"

Final answer = Electic energy =0.3\ kW\ h

Step-by-step explanation:

Electrical Energy E=Power \times time.

The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.

So we have been given the power of the hair dryer =1200\ W =\frac{1200}{1000}=1.2\ kW

Now the time it has been use for =0.25\ hrs

To calculate electric energy we will multiply both the terms.

Electric energy =0.12 \times 0.25 =0.3\ kW\ h

So electric energy used for the hairdryer is =0.3\ kW\ h
