Answer: y > 4.5 or y < -4.5
You use the rule
if |y| > k, then y > k or y < -k
where k is some positive number. In this case, k = 4.5

Plugging in the values from the two matrices will give us the answer A
The answer is 57 because using remote angles theorem you get the largest angle equals to 66 degrees but you are not done yet you have to subtract 66 from 180 because of sum of angles in a triangle so you get 114 degrees and since you have an isosceles triangle you have to divide by two to get y so y = 57 degrees
