Answer:
Area of resulting triangle will be 900 
.
Step-by-step explanation:
When sides of any polygon if scaled by a factor of k
then area is scaled by 
According to the above statement
therefore here in the question since area of original triangle was 36
and both base and height are scaled by a factor of 5.
therefore area of scaled triangle will be 
times of the original
that is 25 x 36 which gives 900
So area of resulting triangle will be 900
In order to answer this one, it's really really really really helpful if you know what the law of cosines says. In fact it's absolutely necessary.
The law of cosines says if you know two sides of a triangle and the angle between them then you can use that information to find the length of the third side.
In the picture you know the lengths of two sides and you know the angle between them. So you can use the law of cosines to find the length of the third sidethat. That's side AC.

Answer: $2.16
Lee watches TV 3 hours per day and TV consumes 200 watts.
Cost of electricity = 12 cents/(1-kilowatt-hour)
200w×3 hours
600 watt-hours
1000 watt-hours=1kwh
1 watt-hours= 1/1000 kwh
600 watt-hours 600/1000=0.6 kwh
0.6×12=7.2cents
1 day=7.2 cents
30 days
7.2×30
216 cents
