Delwyn · Answer

Let another angle be x      According to angle sum property         rm Rrightarrow x+35+78=180       rm Rrightarrow x+113=180       rm Rrightarrow x=180-113       rm Rrightarrow x=67°

67°, every triangle equals 180° so add together 35+78 which equals 113. subtract 180-113 and get 67!
