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 correct first step in finding the area of a base of a cylinder is to find the length of radius of the circular base.
On 6/25 divide 6 by 25=.24 and 2 3/4= 2.75 you have 2 and then 3/4=.75
Let the missing % be x.
Now, according to your question ;
5 = x% of 25
5 = x / 100 * 25
thus, 25x = 500
Thus, x = 500/25
= 20
Thus, 5 is 20% of 25.
Yes.
A fraction means that you divide the top number (numerator) by the bottom number (denominator). So, if you divide 4 by 16, then the answer is 0.25
Another way to get this answer is if you know your basic fraction-decimal conversions. If you reduce the fraction by dividing both the numerator and the denominator by the same number (in this case, 4 works), then you get the fraction 1/4, which is also equal to 0.25
Good luck with your math, and I hope this helps :)
