Question

in the given figure find value of x​

Answer 1

Answer:

120 × 80+100 = 9700.

x=9700.

Answer 2

➠ To Find : the value of x

⟹ we know that a straight line makes 180°

⟹ Then at angle R be y

⟼ y+100° = 180°

⟼ y = 180°-100°

∴ y = 80°

Now, we know that the sum of interior angle of a quadrilateral is 360°

⟼ x°+80°+80°+120° = 360°

⟼ x°+ 280° = 360°

⟼ x° = 360°-280°

∴ x° = 80°
