Answer:
141°
Step-by-step explanation:
It's an octagon so the Sum of interior angles is: (8-2)×180=1080
5x+133+16+126+162-12+30=5x+455=1080
5x=625
x=125
x+16=141
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
Answer:
4y
Step-by-step explanation:
To find the greatest common factor of 2 numbers, factor both of the numbers:
4: 1, 2, 4
12: 1, 2, 3, 4, 6, 12
The greatest factor here in both of these lists is 4. These numbers also both have a factor of y, so you multiply those together and get 4y.
