In a 30-60-90 triangle, the side lengths are in the ratio 1:2:sqrt(3) = short leg: hypotenuse: long leg.
We know the hypotenuse is 8. We can use this to find the other legs.
The short leg s is 8/2 = 4 because the short leg is always half of the hypotenuse.
The long leg q is 4 * sqrt(3), because the long leg is always sqrt(3) times the shorter leg.
So:
s = 4
q = 4 * sqrt(3)
Step-by-step explanation:
18.84/2= 9.42/3.14 = 3 times 3 = 9 times 3.14 = 28.26
answer is 28.26
sorry if i get it wrong this is how i remember finding it. Im very sure this is how it is
Answer: The correct answer is 11 yards of wallpaper border.
Step-by-step explanation: What Wendy needs to do is to calculate the perimeter of her bedroom. The perimeter of any given figure is simply a calculation of the entire measurement all around the given figure. In other words, the perimeter of Wendy's room denotes the addition of all the four side lengths of her bedroom.
The room has two sides both measuring 10 feet 5 inches. This gives a total of 20 feet 10 inches. It also has the other two sides both measuring 6 feet 1 inch and that too gives a total of 12 feet 2 inches. Adding them all together results in 32 feet 12 inches. Better still, the perimeter of the room is derived as;
Perimeter = 2 (L + W)
Perimeter = 2 (10'5" + 6'1")
Perimeter = 2(16'6")
Perimeter = 32'12"
Having in mind our conversion rate of 12 inches equals 1 foot, the results can be properly expressed as 32 feet plus 1 foot which gives us 33 feet.
If the perimeter of Wendy's room is now given as 33 feet, the conversion rate between feet and yards can now be applied. Having been given that
3 feet = 1 yard
Then 1 yard = 3 feet/3, that is
y = 3/3
Hence,
y = 33/3
y = 11
The results show that Wendy would needs to buy a total of 11 yards of wallpaper border.

Answer:
254.8
Step-by-step explanation:
Substitute the numbers where the variables are and do the arithmetic.
4c +2b³ = 4(1.2) +2(5³) = 4.8 +250 = 254.8
