Answer:
There isn't a way to prove that the triangles are similar.
Explanation:
Two triangles are similar if they have the same interior angles and the corresponding sides are proportional.
So, to prove that the triangles are similar we can use:
SSS: The three corresponding sides are proportional
SAS: Two sides are proportional and the angle between them is equal
AA: Two angles have the same measure.
In this case, the yellow angles are equal because they are vertically opposite. They are formed by two lines that intersect.
On the other hand, the side with length 3.6 is corresponding with the side with length 9 but the side with length 4.8 is not corresponding with the side with length 12.
Then, there isn't a way to prove that the triangles are similar.
Answer:
![\displaystyle [-7, -7]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B-7%2C%20-7%5D)
Step-by-step explanation:
{2x - 6y = 28
{−x - y = 14
−⅙[2x - 6y = 28]
{−⅓x + y = −4⅔
{−x - y = 14

Answer:
The length for on side is 10.5.
Step-by-step explanation:
6.5 + 6.5 = 13
34 - 13 = 21
21 divided by 2 is 10.5
Length 10.5 + 10.5 + 6.5 + 6.5 = 34
