Answer:
cos 30 + sin60 + sin30 - cos60
we know that sin ( 90 -a ) = cos a { and vice versa }
therefore by using this property,
sin ( 90 - 30 ) + sin 60 + sin 30 - sin ( 90-60)
sin 60 + sin 60 + sin 30 - sin 30 =
<u>2 sin 6</u><u>0</u>
That's the answer I got. Tell me if it's correct
Answer:
300 squared unit of measurement
Step-by-step explanation:
12*5*5
12*5 = 60
60*5 = 300
I am assuming this is a rectangular prism
The answer is 5 boxes. First we have to do 60 x 2 to find out the area of the walkway (120 ft). Then since the tiles are 2 by 2 feet and come in 6 boxes we do, 2 x 2 to find the area of 1 tile,which is 4 ft, then we multiply that by 6 to find out the total amount of tiles which is 24. We then divided 120 by 24 to find out how much boxes we will need which is 5. Hope that helped :)
Let the answer be x.
Hence, f = x is the answer.
