Answer:
first of all give names to angles which are not given..
let angle between angle c and angle 114 = angle 1
let the angle between angle c and angle 37 = angle 2
now for A
in triangle containing a..
30° + a + angle 1 = 180° [angle sum property in triangle]
now angle 1 = 37° (vertically opposite angle of 37°)
so 30° + 37° + a = 180°
=> 67° + a = 180°
=> a = 180° - 67°
=> a = 113°
angle B =
37° + b + 114° = 180° (linear pair anxiom I.e, sum of all angles at a point is 180°)
=> b = 180° - 151°
=> b = 29°
for C :
angle 2 + c + 37° = 180° (linear pair anxiom)
=> 90° + c + 37° = 180°
=> c = 180° - 127°
=> c = 53°
hence A = 113°
B = 29°
C = 53°
