Answer:
x = 21
Explanation:
The two remaining angles must add to 90 degrees since a triangle adds to 180
3x+6 +x = 90
4x+6 =90
4x = 90-6
4x = 84
Divide by 4
4x/4 = 84/4
x = 21

In this question we are going to speak of point translations. Vectorially speaking, a translation between two points is defined by this expression:
(1)
Where:
- Original point.
- Translation vector.
- Translated point.
If we know that
and
, then the translation vector is:



Therefore, the rule used to translate the image is
