### Geometry Problem: Angle Calculation

#### Given:
Two triangles, ΔSTU and ΔDEF.

**Triangle ΔSTU:**
- Side ST = 15
- Side TU = 10
- Side SU = 20
- Angle ∠TSU = 29°

**Triangle ΔDEF:**
- Side EF = 4
- Side FD = 8
- Side ED = 6
- Angle ∠FED = 46°

**Task:**
Calculate the measure of ∠E and fill in the answer.

#### Options:
1. 46
2. 105
3. 29
4. Can't be determined

#### Explanation of Diagrams:
**Diagram of ΔSTU (Left):**
- A triangle labeled with points S, T, and U.
- Side lengths are marked: ST = 15, TU = 10, SU = 20.
- An angle at point S is marked as 29°.
  
**Diagram of ΔDEF (Right):**
- A triangle labeled with points E, F, and D.
- Side lengths are marked: EF = 4, FD = 8, ED = 6.
- An angle at point E is marked as 46°.

To solve this, you would typically use properties of similar triangles, trigonometric relationships, or congruence criteria. Evaluate which options apply to determine the correct measure of ∠E based on the given information.

#### Answer Selection:
Select one of the following options as the measure of ∠E:
- 46
- 105
- 29
- Can't be determined

Make sure to review the relevant geometric principles and relationships that apply to solving this type of problem.
