Answer:
- SAS
- not
- SSS
- AAS
Step-by-step explanation:
Look at the angles and sides that are marked, and their relationships to each other. Shared sides are congruent to themselves. Vertical angles are congruent. The possible congruence theorems are ...
SSS SAS AAS ASA (and HL for right triangles--not applicable here)
__
1. two marked sides and the vertical angle between are congruent. The triangles are congruent by the SAS theorem.
2. only one side and angle are marked. Insufficient information. Not congruent.
3. two marked sides and the shared side are congruent. The triangles are congruent by the SSS theorem.
4. the vertical angles, the marked angles, and the marked sides are congruent. The triangles are congruent by the AAS theorem.
Answer: Choice C
There is no way to figure out if angle 4 and angle 7 are congruent. If we knew they were right angles, then we would be able to determine that. However, that isn't the case here.
Answer: $4.53
Explanation:
7 dvds cost 31.71 so divide 31.71 by 7
31.71/7 = 4.53
