(1) y = 47°
Since y = 47°, the internal angle of the triangle, that is opposite of angle y is also 47º. Thus, we have 47 + x = 180 => xº = 180 - 47 = 137º. Sufficient.
(2) z = 110°
Since z = 110°, the internal angle of the triangle, that is adjacent to the angle z = 180º - 110º = 70º. Thus, we have 70 + 63 = xº => xº = 137º. Sufficient.
The correct answer: D
Hope this helps!
