Answer: A' (5,9)
Step-by-step explanation:
1. You have that the translation is ⇒ and the coordinates of A is (-2,5). Then:
⇒
2. As you can see, -5 is 7 units below of the line of reflection , therefore, you can know the coordinates of A' as following:
3. Then, the coordinates of A' is (5,9)
Answer:
in steps
DE // BC
m∠ADE = m∠ABC and m∠AED = m∠ACB
∴ ΔADE similar to ΔABC
AB/AD = AC/AE
(AD + DB) / AD = (AE + EC) / AE
AD/AD + DB/AD = AE/AE + EC/AE
1 + DB/AD = 1 + EC/AE
DB/AD = EC/AE (AD/DB = AE/EC)

you round the one and thus 2.1
