Question

in the figure find x.

​

Answer 1

Answer:

Angle formed by a straight line = 180°

=> 30° + x° + 70° = 180°

    100° + x°  =180°

               x°  =  180° - 100°

               x° = 80°

Answer 2

Answer:

80°

Step-by-step explanation:

x+30°+70°=180°(linear pair)

x+100°=180°

x=180°-100°

x=80°
