Find the value of x. ​

Answer 1

Answer:

Required measure of x is 125°.

Step-by-step explanation:

If we observe the diagram, we can easily say that it has four lines and therefore it is a quadrilateral. And we know that the sum of all interior angles { or inferior angles at vertices } is 360°.

Therefore,

= > $\angle$A + $\angle$B + $\angle$C + $\angle$D = 360°

= > 30° + 45° + 50° + $\angle$D = 360°

= > 125° + $\angle$D = 360°

= > $\angle$D = 360° - 125°

= > $\angle$D = 235°

We know that the sum of angles of a particular point is 360°. Therefore the sum of $\angle$D and x should be 360°.

= > $\angle$D + x = 360°

= > 235° + x = 360° { from above $\angle$ D = 235° }

= > x = 360° - 235°

= > x = 125°

Hence the required measure of x is 125°.
