Answer:
C
Step-by-step explanation:
The angle adjacent to x on XY = 115° ( corresponding angle )
This angle and x are adjacent and supplementary , thus
x = 180 - 115 = 65 → C
Answer:
46.66%
Step-by-step explanation:
42/90 = x/100
find x
multiply 42 times 100 and divide by 90
After you have multiplied but you have all these numbers, look to see how many decimal places the numbers you have multiplied.
Lets say you multiply:
23.45
x 2.1
= 49.245
Because your first number had 2 decimal places and your second number had 1 decimal place you add that and that is how many decimal places your product has. In this case there is three.
In probability, problems involving arrangements are called combinations or permutations. The difference between both is the order or repetition. If you want to arrange the letters regardless of the order and that there must be no repetition, that is combination. Otherwise, it is permutation. Therefore, the problem of arrange A, B, C, D, and E is a combination problem.
In combination, the number of ways of arranging 'r' items out of 'n' items is determined using n!/r!(n-r)!. In this case, you want to arrange all 5 letters. So, r=n=5. Therefore, 5!/5!(505)! = 5!/0!=5!/1. It is simply equal to 5! or 120 ways.
