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 :)

Answer:
Step-by-step explanation:
Given points are
And given transformation is
We will start from left to right.
First transformation is reflection about x-axis.
When we reflect about x-axis
So,
Now next transformation is dilation with a factor 4.
If we do dilation with a factor to the point
New co-ordinates after dilation became
So,
