The outside arcs for a circle enveloping a triangle will always equal 360.

Set up an equation that has all arcs equal 360:

(3x + 30) + (5x + 10) + (2x + 20) = 360

Combine like terms:

3x + 5x + 2x = 10x
30 + 10 + 20 = 60

10x + 60 = 360

Subtract 60 from both sides:

10x = 300

Divide both sides by 10 to get x by itself:

x = 30

We can now find the values of the arcs:

3(30) + 30 = 90 + 30 = 120
5(30) + 10 = 150 + 10 = 160
2(30) + 20 = 60 + 20 = 80

All three arc lengths are different, which means that the triangle's side lengths are all different. This makes the triangle a scalene triangle.

5x-8y=40 what is the x intercept
Artist 52 [7]
Hello! The x-intercept is where the line crosses the x-axis when y = 0. We already have the expression shown. We will plug in 0 as y to get this:

5x - 8(0) = 40.

As you probably know, anything times 0 is 0, so -8 * 0 is 0. All we have is 5x = 40. Divide each side by 5 to isolate the x. 5x/5 cancels out. 40/5 is 8. There. x = 8. The x-intercept is (8, 0).
