1------x=40°

2------x=35°

Answer 2

Answer: (i) 40

              (ii) 35

Step-by-step explanation:

(i) :

2x + x = 120                              [exterior angle = sum of internal opp angles]

[OR through angle sum property we will obtain the same result]

3x = 120

x = 120/3 = 40

(ii) 55 + 90 + x = 180                       [Angle sum property of a triangle]

   145 + x = 180

    x = 180 - 145 = 35
