Question

Find the value of x in the given figure.

1. 30
2. 60
3. 90
4. 180​

Answer 1

Answer:

The value of a quadrilateral is 360°.

so,

$130°+120°+50°+x=360°$

=>$300°+x=360°$

=>$x=60°$

Answer 2

Step-by-step explanation:

According to angle sum property of a quadrilateral we have sum of all angles in a quadrilateral equal to 360°

Then , 50° + 130° + 120° + x = 360°

=> 300° + x = 360°

=> x = 360° - 300° = 60°

Therefore required value of x is equal to 60 degree equal to option (2) 60
