Question

angle dab =40 degrees angle dcb = x find the x​

Answer 1

Answer:

In □ACDE,

∠DEB=90

o

−44

o

=46

o

Also, AC∣∣ED and hence, ∠ABE=∠DEB=46

o

Now, ∠ABE+∠EBC=180

o

∴∠EBC=134

o

In □DCBO, Sum of each angle should equal to 360

o

and Hence,

134

o

+90

o

+57

o

+x

o

=360

o

∴x=79
