Answer 1

Answer:

a = 45

b = 45

d = 135

Step-by-step explanation:

b =45 (vertically opposite angles)

a = 45 (alternative angles of a transversal)

Answer 2

Answer:

Hope you can understand it easily. . . . . . . . . . . . . .

Step-by-step explanation:

Here ,∠b=45°(Vertically opposite angles )

Now,∠a=∠b (alternate interior angles)

Hence ,∠a=45°

also,∠c=∠a (Vertically opposite angles)

Hence, ∠c=45°

Now,∠c +∠d=180°(Linear pair )

or,45°+∠d=180°(because ∠c%45°)

or,∠d=180°- 45°

or, ∠d=135°

Hence, ∠a=45°∠b=45°∠c=45°∠d=135°.
