Hello! I am happy to help you.

Here, x=36.

2*36=72*2=144+36=180. A triangle's measure equals 180.

Hope this helps!

Which vector best describes the translation below?

<h3>Answer: Choice A) <9,0></h3>

Explanation:

Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)

Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule $(x,y) \to (x+9, y)$ . We've added 9 to the x coordinate, and the y coordinate stays the same.
