Question

calculate the value of xin the given figure ​

Answer 1

Answer:

x =  130°

Step-by-step explanation:

We know, the sum of the angles of a quadrilateral is 360°.

⇒ 45° + 55° + 30° + ∠ BDC = 360°

⇒ 130° + ∠ BDC = 360°

⇒ ∠ BDC = 360° - 130°

⇒ ∠ BDC = 230°

Now, we know that

x + ∠ BDC = 360°

⇒ x + 230° = 360°

⇒ x =  360° - 230°

⇒ x =  130°
