Answer:
x - y = 3
2x - y = 2
Step-by-step explanation:
x = 3 + y
2(3 + y) - y = 2
6 + 2y - y = 2
y = 2 - 6
y = -4
x = 3 + (-4)
x = 3 - 4
x = -1

Answer:
Step-by-step explanation:
We can note a couple of relationships in this circle.
The arc length will be a fraction of the circumference. It will be the same fraction of the circumference that the central angle is to the entire circle.
<u>First step: Find the circumference of the circle</u><u>.</u>
The circumference of any circle can be defined by the formula , where r is the radius of the circle. The radius is given to us, 30 in. We can now substitute that into the formula.
So our circumference is 60π.
<u>Second Step: Find the ratio of the central angle of the arc to the total circle degrees</u>
We know that the total amount of degrees in a circle is 360°. Therefore, we can set up a proportion to find the ratio between the central angle (90°) and the total circle measurement.
<u>Third Step: Equal out the two proportions and solve for the missing arc length</u>
Now that we have our base proportion (), we can turn 60π into a proportion as well, leaving 60π as the denominator so we can solve for the arc length.
We can now solve for x by cross multiplying.
Hope this helped!
