Question

Help please. Let me know what applies.

Answer 1

`\tt Step-by-step~explanation:`

`\tt~1:`

First, let's observe the diagram. line a is parallel to line b, so that means ∠2 and ∠6 are congruent. They are corresponding angles.

`\tt 2:`

If ∠2 and ∠6 measures 78º, then that means the angles that are vertical to these angles, ∠4 and ∠8, are also congruent to each other.

`\large\boxed{\tt Our~final~answer:Angles~4,6,8}`

If you would like to know what the other angles' measures are, you could simply subtract 78º from 180. A straight line measures 180º.

`\large\txt{\tt 180-78=102}`

`\small\boxed{\tt Other~angles'~measures:~102}`
