Given thаt is 51 degrees, is equаl tо , аnd is equal tо , what is the degree оf ? The three black rays extend from a central blue point labeled Y. One ray extends diagonally upward to the right and ends at point X, another goes horizontally to the right with no endpoint labeled, and the third extends diagonally downward to the right, ending at point Z. The angles formed between the rays are labeled as angle one (between XY and the horizontal ray) and angle two (between ZY and the horizontal ray). All labeled points, X, Y, and Z, are marked with blue dots, and each ray has an arrowhead to indicate direction, away from point Y.
