Answer 2

HEYA SHIVANSH HERE!!!

Answer:

Angle A = 70

Angle B = 150

Angle C = 140

Angle i = 110

Step-by-step explanation:

Angle B + 30 = 180 (linear pair)

Angle B = 180 - 30

Angle B = 150

Angle C + 40 = 180 (linear pair)

Angle C = 180 -40

Angle C = 140

=> Angle A+ Angle B+ Angle C =360 ( sum of all three exterior angles of a triangle is 360)

   Angle A + 150+140= 360

   Angle A =360- 290

   Angle A = 70

=> Angle i + Angle A = 180 (linear pair)

    Angle i + 70 = 180

Angle i = 110
