figure.
Please give step wise explanation of the question
Figure is already given.​

Answer 1

Answer:

X=110⁰

2(angleA)=angleD

Answer 2

Answer:

well so step by step explanation

ABDC is quadrilateral, and sum of angles of quadrilateral is 360. then:

angle A + angle B + angle C + angle D = 360°

55° +45° + 30° + angle D = 360°

130° + angle D = 360°

angle D = 360° - 130°

angle D = 230°

so we have interior angle CDB as 230°

and we have to find exterior angle CDB(x)

so you may know that sum of x and interior angle CDB will be 360°

so, by that we can get angle x as 130°

but if u need explanation of that simple thing it's here:

x + interior angle CDB = 360°

x + 230° = 360 °

x = 130°

hope you got your step by step explanation

if u got what u needed u can mark it as brainlist
