Answer 1

Answer:

109 degrees

Step-by-step explanation:

In the given figure,

ABCD is a quadrilateral.

A+B+C+D=360 [Sum of interior angles of a quadrilateral=360 degree]

So,

34+45+30+D=360

=> 109+D=360

=>D=360-109

=>D= 251 degrees

Now,

angle D + x= 360 [sum of angles at a point=360]

so, putting D=251

251+x=360

x= 360-251

x= 109
