Answer 2

Answer Z = 45 degree , Y= 135 Degree and U = 135 degree

Step-by-step explanation:

X = Z as they are vert. opp. angles

and Y = U as they are vert. opp. angles.

so, X+Y= 180 degree (linear Pair)        (eq 1 )

and U + Z = 180 degree.                      (eq 2)

so , GIven X= 45 deg

45 deg + Y = 180 deg.

Y= 135 deg.

Now, X= Z as stated above

so, Z = 45 deg

and Y = U

as stated above

so , U= 135 deg.
