Answer:

12

Step-by-step explanation:

In order to answer this question, you need to make an equation in the format of mx+b=y. This equation would look like this:

5x-12=48

Then, just solve for x. First, you would do the opposite of what your b is doing to both sides to move it. For instance, your b is being subtracted. So, add it to both sides to move it. It would then become:

5x=60

Then, you would do the opposite of what your m is doing to both sides to move it. So in this equation, you would divide both sides by 5. It would then give you:

x=12

Someone help me fast please
lions [1.4K]

Answer:

86

Step-by-step explanation:

<u>Perimeter of WXY = WSY+WRX+XY</u>

<em>--> WSY = SY x 2</em>

--> WSY = 16 x 2 = 32

<em>Since it is an isosceles triangle, WRX = WSY</em>

--> WRX = 32

<em>--> Draw a straight line from W to XY to divide it into two halves assuming it to be point A. This would form a right angle triangle of WAX.</em>

<em>--> Solve it using the cos theta rule</em>

--> Angle = Angle X = 70°

    Hypotenuse = WRX = 32

    Adjacent = WA = ?

<em>--> Cos (Angle) = Adjacent/Hypotenuse</em>

    Cos (70) = WA/32

    WA = 10.9 rounded off to 11

--> WA=AY= 11

--> XY = WA + AY = 11+11 = 22

<em>--> Perimeter = WSY+WRX+XY</em>

    Perimeter = 32+32+22

    Perimeter = 86

Therefore, the perimeter of WXY is 86.
