21 because you have to have at least 1 side as 3m so the other two should be 9m to have the greatest possible length
In a circle, the internal vertical angles have a formula of

In this case, the formula would be:

We know that whole circle is 12x. And 12x is equal to 360°. When we put that into equation:


If x is 30°:

So, angle 7 is 90°.
The answer is quite simple after looking at it. 0.1 is a tenth. 72 is a whole number, so you would have 72 1/10. 1/10 is a tenth and 72 is still the whole number.
Hello!
We could write this as an equation below.
0.76x=703
We divide both sides by 0.76.
x=925
Therefore, the regular price is $925.
I hope this helps!
