I added the diagram of the question.

<u><em>Answer:</em></u>
h = 60°

<u><em>Explanation:</em></u>
We are given that lines k and l are parallel lines.
This means that angles 120° and h are <u>supplementary angles</u>.
This means that their measures <u>add up to 180°</u>

<u>Therefore:</u>
180° = 120° + h
h = 180° - 120°
h = 60°

Hope this helps :)

Lemur [1.5K]

Answer:

7/12

Step-by-step explanation:

12 sided die has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 as the sides.

Two digits are 10, 11, and 12.

Even numbers are 2, 4, 6, 8, 10, and 12.

So two digits or even numbers are 2, 4, 6, 8, 10, 11, and 12. (7 total numbers)

P(Two digits or even) = 7/12
