Answer 2

x = 80°

Step-by-step explanation:

In the given figure,

Let the angle 'y' as a interior angle of this quadrilateral.

So,

y + 90° = 180°....[linear pair]

=> y = 180° - 90°

=> y = 90°

Now,

Sum of all angles of a quadrilateral = 360°

=> 120° + y + 70° + x = 360°

=> 120° + 90° + 70° + x = 360°

=> 280° + x = 360°

=> x = 360° - 280°

=> x = 80°

So,

The value of 'x' is 80°.

Hope it helps.
