Question: 2

Difficulty: medium



since angles on a line add to 180°, we know that ∠BAC = 55°
Image


Since AC = BC, we know we have an ISOSCELES triangle, which means ∠CAB = ∠CBA, which means ∠CBA = 55°
Image



Since angles in a triangle add to 180°, we know the missing angle (aka x) is 70°
Image


Finally, since angles on a line add to 180°, we know that y = 125°
Image



Answers: x = 70, and y = 125
