The answer is A. Angles of a triangle will always add up to 180. If you add up 70+67+57 you are left with 194, which is 14 more than 180. Because we need to be at 180, we can assume that x is a negative number. If we say x is negative 7 we are able to takeaway 7 from 67 and 57. After this, we see that the sum of our angles is 50+60+70=180. Therefore, x=-7 in this situation and angle A is equal to 60. The answer is A.

10 students of Elena's classmates like to make jewellery.

Step-by-step explanation:

Let total no.of classmates who liked the jewellery = x

Here, in the given problem, given she asked her classmates '20'. So, it clearly shows that total number of students/classmates = 20. Also, in that, 50% said like to make jewellery. Now find 'x' as below,

$x = 50 \% \text { of } 20$
