Question

what is the answer for this question​

Answer 1

Answer:

45 45 135 135

Step-by-step explanation:

x=45

x=z(vertically opposite angles)

therefore z=45

z+y=180(angles in a straight line)

y=180-45

y=135

y=w(vertically opposite angles)

w=135

Answer 2

Answer:

x = 135°

z = 45°

u = 135°

Step-by-step explanation:

z = x 45° ( Vertically opposite angles )

z + y = 180° ( Linear Pair )

y = 180° - 45°

y = 135° = u ( Vertically opposite angles )
