An exterior angle is equal to the two opposite inside angles.
You are given the exterior angle and the two opposite inside angles so you can set up an equation to solve for x, then replace x in the equation to solve for the angle.
7x-16 = 4x + x+8
Simplify:
7x-16 = 5x+8
Add 16 to each side:
7x = 5x+24
Subtract 5x from each side:
2x = 24
Divide both sides by 2:
x = 24/2
x = 12
Now replace x with 12:
7(12)-16
Simplify:
84 -16
Subtract:
Answer is 68 degrees.
The correct answer is

Step-by-step explanation:
The Circumference of a circle can be displayed by this formula:
is the circumference, and is the radius.
So just plug in 31 for , and simplify:
Because the question is asking for the diameter, we only need to divide both sides by pi, as is the same thing as diameter.
(rounded to the nearest hundredth)
We can even rewrite as , which stands for diameter, to make things a little simpler.
Now we just take 9.87, and round it to the nearest whole number, and we get 10. So your answer is 10 Inches.
Hope it helps, have a fantastic day.
Answer:
B
Step-by-step explanation:
The simplest way to do this is to take every integer on there and divide it by 3.
8961/3 = 2987
5233/3 = 1744 1/3
10245/3 = 3415
-5469/3 = -1823
Because B does not produce an integer, that is your answer
(This works because of inverse operations)
