1.	\left. \begin{array} { l } { 55 ^ { \circ } , 65 ^ { \circ } , 60 ^ { \circ } } \\ { 125 ^ { \circ } , 45 ^ { \circ } , 35 ^ { \circ } } \\ { 115 ^ { \circ } , 35 ^ { \circ } , 30 ^ { \circ } } \end{array} \right.
Answer» option A and option C are the correct answers. The sum of angles of a triangle is 180°. therefore by adding the above angles, 55°+65°+60°= 180° and115°+35°+30 = 180°
