By applying the knowledge of similar triangles, the lengths of AE and AB are:
a. ![\mathbf{AE = 3.9 $ cm}\\\\](https://tex.z-dn.net/?f=%5Cmathbf%7BAE%20%3D%203.9%20%24%20cm%7D%5C%5C%5C%5C)
b. ![\mathbf{AB = 2.05 $ cm} \\\\](https://tex.z-dn.net/?f=%5Cmathbf%7BAB%20%3D%202.05%20%24%20cm%7D%20%5C%5C%5C%5C)
<em>See the image in the attachment for the referred diagram.</em>

- The two triangles, triangle AEC and triangle BDC are similar triangles.
- Therefore, the ratio of the corresponding sides of triangles AEC and BDC will be the same.
<em>This implies that</em>:

Answer:
what is the question and give the question first
Answer:
(-3,4)
Step-by-step explanation:
That means to reflect the point across the y-axis... If you draw (3,4) on the coordinate plane you should see (-3,4) is the reflection across the y-axis from that point.
Triangle BCG or d I'm pretty sure . Hope I'm right :)
