Question

Lines g, h, and l are parallel and m 2 = 115°.

What is m11?


35°

65°

115°

145°

Answer 1

`m\:<\:11=115\degree`

Explanation:

We were given that
`m\:<\:2=115\degree`.

Since line
`g,h` and
`l` are parallel lines,

it means that,
`m\:<\:2=m\:<\:6=m\:<\:10=115\degree`.

The reason is that corresponding angles are equal.

We can also observe that
`m\:<\:11=m\:<\:10`, because vertically opposite angles are equal.

Therefore
`m\:<\:11=115\degree`.

Hence the correct answer is C
