Answer:
x = 20º
Explanation:
Since it is a triangle, the sum of the internal angles is 180º.
We know that y = 90º, because 110º + 70º = 180º, and the line intercepts it, splitting the larger triangle into 2.
Since, y = 90º, and the other angle is 70º, we add those together to 160º.
Then, we take 180º - 160º = 20º.
x = 20º
Hope this helps.
