Hard to know if ZY is closer to 30 or to 34. One of those. To be more sure, use Law of Sines.
---- the sines and the angles go in the same order direction, so this value is difficult to judge. Computing gives
The Angle A question uses Law of Cosines. Fitting the images values directly into the law's equation, .
You solve for A!
