What is the missing angle of this triangle ?

61             33

61° + 33° + ? = 180°
94° + ? = 180°
= 180° − 94°
 = 86°

What is the missing angle of this triangle ?

53                37

53° + 37° + ? = 180°
90° + ? = 180°
= 180° − 90°
= 90°

76° + 68° + 147° + ? = 360°
291° + ? = 360°
= 360° − 291°
= 69°
