angle A = 70 °
angle B = 55°+12° = 67°
angle C = x
A + B + C = 180° ( triangke sum property)
70°+67°+x =180°
137 + x = 180°
x = 180-137
x = 43°
angle B = 55°+12° = 67°
angle C = x
A + B + C = 180° ( triangke sum property)
70°+67°+x =180°
137 + x = 180°
x = 180-137
x = 43°

why r u doing 55+12
coz angle B is divided into two parts if we would plus both the two then we will get the complete angle b

70+55+12=137
total sum of angles in triangle is 180
therefore
137+x=180
x=43
