This doesn't make sense...

You didnt tell us what the radius was.

"Three circles are drawn, so that each circle is externally tangent to the other two circles. Each circle has a radius of (where is it???). A

The three angles of a triangle added up are always 180 degrees. Therefore, you can add 94 and 41 to get 135. Next, 180 minus 135 is 45. now we can do the same thing. 45+111 is equal to 156. Now you subtract to get x = 24.

Because a prime number is a number that can not be divisible by any number except for itself and one, you can just list the prime numbers under and/or equal to 30. Every composite, or non-prime, is divisible by at least two prime numbers.

im not sure.... i also have that exact question
