What equals 17 using the numbers 8 1 5 4 4 in order?
The only way I can see to reach the answer of 17 is: 8 + 15 + 4 + 4 = 8 + 1 + 4 + 4 = 17. I hope that using the "5" as a power is acceptable.
Why isn't 15 a prime number?
A number is prime if it has only 1 and itself as factors. For example, 7 is a prime number because it has only 1 and 7 as factors. 15 isn't a prime number because it has 1, 3, 5, and 15 as factors.
What is the measure of an angle of 15 side shape?
A 15 sided shape's total number of degrees can be found using the formula (x-2)*180, where x is the number of sides. Using this we find that a 15 sided shape's total degrees is 2340. Divide that number by 15 to get the degrees of each interior angle. It comes out to be 156 degrees.
