Sine = opposite / adjacent.

since the opposite and adjacent lines are used, you need to use some to solve for x.

Answer:

The correct answer is A which is sine.

Step-by-step explanation:

The variable x is opposite to the known angle and the known side length which is the hypotenuse.

Recall the mnemonics SOH, which means that,
the sine ratio involves the length of the opposite side and the hypotenuse.

That is,

\sin50\degree=\frac{opposite}{hypotenuse}

\sin50\degree=\frac{x}{2}

We can use this to solve for x.

Tina uses 50$ gift certificate to buy a pair of pajamas for 17.97, a necklace for 25.49, and 3 pairs of socks that each cost the
Gwar [14]
17.97 + 25.49 + 3x = 50.33
17.97 + 25.49 + 3x - 17.97 - 25.49 = 50.33 - 17.97 - 25.49
3x = 6.87
3x/3 = 6.87/3
x = 2.29 per pair of socks

How do you make 22 percent into fraction in simplest form
exis [7]

22% in fraction form is 22/100 or 0.22, but it isn't the simplest form.

To put 22/100 into a simplest form, you must divide the numerator <em>and </em>the denominator by a common multiple.

22/100 or 0.22 is divisible by 2. Therefore, you can divide 22/100 by 2.

Equation:

22/100 divided by 2/2 =  11/50

Hence your answer, 11/50

Hope this helps!

The length of a rectangle is 2 units more than the width. The area of the rectangle is 63 units. What is the length, in units, o
Keith_Richards [23]

Answer:

Length = 9units

Width = 7units

Step-by-step explanation:

It is said that the length is 2units more than the width

Assume that the width is x, then the length will be 2 + x

ie

Width = x

Length = 2 + x

Area of the rectangle = 63units

Area of rectangle = l * b

l - length of the rectangle

b - width of the rectangle

A = l * b

63 = (2 + x) * x

63 = ( 2 + x) x

63 = 2x + x^2

Let's rearrange it

x^2 + 2x - 63 = 0

Let's find the factor of 63

A factor that can be multiplied to give -63 and that can be added to give +2

Let's use -7 and +9

x^2 - 7x + 9x - 63 = 0

Separate with brackets

( x^2 - 7x) + ( 9x - 63) = 0

x( x - 7) + 9(x - 7) = 0

( x + 9)(x - 7) = 0

( x + 9) = 0

( x - 7) = 0

x + 9 = 0

x = -9

x - 7 = 0

x = 7

Note: the length of a rectangle can not be negative

So therefore,

x = 7

Length = 2 + x

= 2 + 7

= 9units

Width = x

= 7units
