Answer:
in steps
Step-by-step explanation:
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)
Answer:
-30.6
Step-by-step explanation:
You can use a calculator or you can think and be well if theres a number line theres a right part so -100.55 so then yo move 69.95 spaces
Answer:
Step-by-step explanation:
ACB is an inscribed angle
so ∠ACB = 1/2 mAB
Hence we got

1. addition
2. subtraction
3. division
