If a triangle has angle measures of x, y, and z, what is the value of x?
(1) y + z = 130
(2) x + y = 98
The OA is A.
I'm really confused with this DS question. Please, can any expert assist me with it? Thanks in advanced.

Since the sum of all the angles of a triangle is 180º, x + y + z = 180.
Thus, x = 180 - (y + z) => x + 180 - 130 = 50º. Sufficient.
(2) x + y = 98
Can't get the value of x with this information. Insufficient.
The correct answer: A
Hope this helps!
