Asap urgent full explaination i will mark brainliest

Answer 1

Answer:

here, bca=110  opposite angles of parallelogram are equal

then,

z+110=180  linear pair

or,z=180-110

or,z=70

now,

25+y+110=180   sum of angles of a triangle

or,135+y=180

or,y=180-135

y=45

also,

(x+25)+110+110+y+dca=360  sum of angles of parallelogram

x+dca=360-245

x+dca=115     (i)

x+25=y+dca  opposite angles of parallelogram are equal

x+25=45+dca

x-dca=45-25

x-dca=20   (ii)

solving them

2x=135

x=135/2

x=67.5
