<A= 23°
< B = 26°
23+26+c= 180°
49+c= 180°
c= 180-49
<C= 131°

Answer:
angle A = 23 degree, angle B = 26 degree, angle C = 131 degree
Step-by-step explanation:
angle A = 23 degree
angle B = 26 degree
angle C = ?
⇒angle A + angle B + angle C = 180 degree (Angle Sum Property)
23 degree + 26 degree + angle C = 180
49 degree + angle C = 180
angle C = 180 - 49 degree
angle C = 131 degree
⇒ hence, angle A = 23 degree
angle B = 26 degree
angle C = 131 degree
