$\huge\color{pink}{⇝}$W.K.T,

Total angle in triangle=180°

i.e., 30°+40°+x=180°

=70°+x=180°

x=180°-70°=110°

so the other angle is 110°

Answer 2

Answer:

2) 110 degree is the answer.

Step-by-step explanation:

Sum of angles of a triangle = 180 degree

angle 1 + angle 2 + angle 3 = 180 degree

30 degree + 40 degree + angle 3 = 180 degree

70 degree + angle 3 = 180 degree

angle 3 = 180 degree - 70 degree

angle 3 = 110 degree
