Answer:
5/4
Step-by-step explanation:
10/12×6/4
60÷48=1.25 or 5/4
Drawing a diagram to match this figure, BC would have to be the hypotenuse as it is the longest side of the triangle. Angle A would have to be the right angle.
For the first choice,
![\cot B = \frac{1}{ \tan B} \\ = \frac {1}{\frac {6}{5}} \\ = 1 \div \frac{6}{5} = \frac{1}{1} \div \frac{6}{5} \\ = \frac{1}{1} * \frac{5}{6} = \frac{5}{6}](https://tex.z-dn.net/?f=%5Ccot%20B%20%3D%20%5Cfrac%7B1%7D%7B%20%5Ctan%20B%7D%20%0A%5C%5C%20%3D%20%5Cfrac%20%7B1%7D%7B%5Cfrac%20%7B6%7D%7B5%7D%7D%0A%5C%5C%20%3D%201%20%5Cdiv%20%5Cfrac%7B6%7D%7B5%7D%20%3D%20%5Cfrac%7B1%7D%7B1%7D%20%5Cdiv%20%5Cfrac%7B6%7D%7B5%7D%0A%5C%5C%20%3D%20%5Cfrac%7B1%7D%7B1%7D%20%2A%20%5Cfrac%7B5%7D%7B6%7D%20%3D%20%5Cfrac%7B5%7D%7B6%7D)
. The first choice is not correct.
The second choice gives us
![\csc C= \frac{1}{ \sin C}= \frac{1}{\frac {5}{8}} \\ = 1 \div \frac{5}{8} = \frac{1}{1} \div \frac{5}{8} \\ = \frac{1}{1} * \frac{8}{5} = \frac{8}{5}](https://tex.z-dn.net/?f=%5Ccsc%20C%3D%20%5Cfrac%7B1%7D%7B%20%5Csin%20C%7D%3D%20%5Cfrac%7B1%7D%7B%5Cfrac%20%7B5%7D%7B8%7D%7D%0A%5C%5C%20%3D%201%20%5Cdiv%20%5Cfrac%7B5%7D%7B8%7D%20%3D%20%5Cfrac%7B1%7D%7B1%7D%20%5Cdiv%20%5Cfrac%7B5%7D%7B8%7D%0A%5C%5C%20%3D%20%5Cfrac%7B1%7D%7B1%7D%20%2A%20%5Cfrac%7B8%7D%7B5%7D%20%3D%20%5Cfrac%7B8%7D%7B5%7D)
. The second choice is not correct either.
The third choice gives us
Answer:
12 + 12 = 24
Step-by-step explanation:
P = 2L + 2W
P = 2*16 + 2W
P = 56
56 = 32 + 2W Subtract 32 from both sides
56 - 32 = 2W
24 = 2W Divide by 2
24/2 = 2W/2
12 = W
The answer you want is 2 * 12 = 24
Answer:
n = ±6 .
Step-by-step explanation:
A quadratic equation is given to us and we need to find out the solution of the given equation . The given equation is ,
Subtracting 18 both sides ,
Multiplying both sides by -2 ,
On simplyfing , we get ,
Putting squareroot both sides ,
This equals to ,
<u>Hence</u><u> the</u><u> </u><u>value</u><u> of</u><u> </u><u>n </u><u>is </u><u>±</u><u>6</u><u> </u><u>.</u>
