You start at 18 feet, go down to -14, go down 4 feet to -18 feet or C
<h3>
<u><em>We need to solve for the angle VXY and it is equivalent to (18x - 2)°. We all know that the total angle of the given figure is 106°, so by adding the angles of the four sides, we can solve for the value of x. The solution is shown below:</em></u></h3>
<em>∠WVX + ∠VXY + ∠XYW + ∠YWV = 360°</em>
<em>Substituting their values, we have:</em>
<em>90° + (12x + 2)° + 90° + (18x -2)° = 360°</em>
<em>Perform addition and subtraction</em>
<em>90 + 12x + 2 +90 + 18x -2 = 360</em>
<em>30x + 180 = 360</em>
<em>Transpose 180 to the right side such as:</em>
<em>30x = 360 -180</em>
<em>30x = 180</em>
<em>Solve for x, we have:</em>
<em>x = 180 / 30</em>
<em>x = 6</em>
<em>Solving for the angle VXY, we have:</em>
<em>∠VXY = 12X + 2 = 12(6) + 2</em>
<em>∠VXY = 74°</em>
<em>The answer is 74°.</em>
Answer:
There are many answers, but one example would be (1, 13)
Step-by-step explanation:
In order to find this, we simply need to select an x and it will help us find y. Our x for this case will be 1. Now we put that into the equation and solve for the y value.
y = 4x + 9
y = 4(1) + 9
y = 4 + 9
y = 13
This gives us the ordered pair of (1, 13)
The formula for the circumference of a circle is 2•Pi•R (radius)or Pi•D (diameter).
Since we have the Radius, 5, let's use the 2•Pi•R path.
Pi is defaultly used as 3.14
Plug in 5 for R.
2 • 3.14 • 5
2• 5 = 10
10 • 3.14 = 31.4
The circumference of your circle is 31.4 CM.
Answer: 31cm
I hope this helps!
