A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81

Answer:

Option B: 600 is the correct answer.

Step-by-step explanation:

In order to solve this question, we will first find the probability or ratio of people out of 200 who will love to have pig as a pet

We know that

Sample size = n(S) = 200

Let A be the event that people will pick pig as pet

Number of people who pick pig = n(A) = 12

Thus the probability is:

$P(A) = \frac{n(A)}{n(s)}\\= \frac{12}{200}\\= 0.06$

0.06 is the probability for the sample of 200. To find it for the whole population we will simply multiply the probability with population size.

So,

$=0.06*10000 = 600$

Hence,

Option B: 600 is the correct answer.

<span>
Assign variables :
Let x = first consecutive even
Let x + 2 = second consecutive even
Let x + 4 = third consecutive even
4x = 6 + 2(x+4)
4x = 6 + 2x + 8
4x = 2x + 14
4x - 2x = 14
so your answer is 7,9and 11</span>
