Alrighty, so:
Question 9.) We know that each box has a total of three toys, therefore whatever answer we choose must be a multiple of 3. Answer E.) 12 is the only multiple of 3.
Question 10.) The numbers are going up by 13. 63 is what I got as the answer.
Question 11.) A
Question 12.) A
Hope this helps! Been a while since I've done math like this.
The answer is 6300 degrees
Atomic number cannot be same and also atomic number can also be called an unique ID of an element.
If we want to calculate a, then cos(60°) = a/12, but we know that cos(60°) = 1/2,
then 1/2 = a/12 and a = 6
If we want to calculate b, then sin(60°) = b/12, but we know that cos(60°) = (√3)/2
then (√3)/2 = b/12 and b = 6√3
