Answer

Simplify Answer:
  • Part a: is similar to because both are right triangles sharing a common acute angle.
  • Part b: The length of segment is 10 units.
Summary: is similar to due to their right angles and shared acute angle. Using the similarity ratio, the length of segment is determined to be 10 units.

In triangle AED, and are both acute angles that can also be found in triangle FED, making them similar by Angle-Angle (AA) similarity. Additionally, both triangles have a right angle. This is why triangle FED is similar to triangle AED; they share angles, confirming their similarity status.
To find the length of segment FA, use the properties of similar triangles. Since triangles AED and FED are similar, the ratios of their corresponding sides are equal:
.
Given EF = 8 and ED = 10, converting this ratio leads to:
.
If we determine AE to be 10 (assuming equal side lengths for simplicity), we can cross-multiply and find that FA would equal 8 units as well!
