Answer:
The answer is option B
Explanation:
Since the figure above is a triangle all it's interior angles sum up to 180°.
To find y add up all the angles and equate them to 180 and solve for y
That's
y + y - 12 + 56 = 180
2y + 44 = 180
2y = 180 - 44
2y = 136
Divide both sides by 2
We have the final answer as
y = 68°
