Question

Please help! I don't know what answer b is, but i know a, thank you.

Answer 1

They are corresponding angles

Explanation:

We know that x=75⁰ because

`180 - 105 = 75`

75⁰ is angle EFB

Since we know this, and because we know that AD//EH,

We can conclude that x=75⁰(AD is parallel to EH and angle CBA or x and angle EFB are corresponding angles)
