Answer:

c = 25, d = 65

Step-by-step explanation:

∠d + 90 = 155 ( vertical angles )

Subtract 90 from both sides

d = 65

The angle above 155 = 180 - 155 ( straight angle ) = 25

Hence c = 25 ( corresponding angles )

Answer:

<d = 65 degrees.

<c = 25 degrees.

Step-by-step explanation:

<d + 90 = 155 since vertically opposite <'s are equal. Therefore <d = 155-90

= 65 degrees.

The angle adjacent to <d is 180-155= 25 degrees since <'s on a line = 180 degrees.

Therefore <c= 25 degrees since corresponding <'s on parallel lines are equal.
