Answer:

x=12

Step-by-step explanation:

we know that the sum of the angles in a triangle is 180 degrees

to find x we have to calculate the sum of the angles

(10x-11)+(3x-2)+(3x+1)=180

10x-11+3x-2+3x+1=180

16x-12=180

16x=180+12

16x=192

x=192/16=12

Arc length is the angle/360 times circumference. The diameter of the unit circle is 2. So the circumference of the unit circle is 2pi, if you use 3.14 for pi, then the circumference is 6.28. So your equation is
x/360 times 6.28=4.2, divide by 6.28, then multiply by 360
x=240.76432
Your answer rounded to the nearest thousanth is 240.764
