Find the value of x and y. triangle The angle above adjacent to the inner segment and left adjacent to the right side is labeled left parenthesis 2 x plus 7 right parenthesis degrees. The angle lower adjacent to the inner segment and left adjacent to the right side is labeled left parenthesis 12 y plus 1 right parenthesis degrees. The lower right interior angle of the triangle is labeled left parenthesis 3 x minus 7 right parenthesis degrees. A. x = 15, y = 12 B. x = 14, y = 11 C. x = 14, y = 12 D. x = 15, y = 11
