Answer 2

Answer:

Q)-TO SOLVE X IN THE ∆'le

Step-by-step explanation:

A) -

As, in the angle DBC the straight line = 180°

Then,Angle ABC = 180° - 120°

= 60°

THEN...

AS A + B + C = 180°

x + 60° + x + 30° = 180°

2x + 90 ° = 180°

2x = 180° - 90°

2x = 90°

x = 90°/2

x = 45°

therefore , x = 45°

x + 30° = 45°+30°

=75°
