B = 120 because it is in your sum
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)
Since he deposited 160 then took out 160 it did not change
Answer:
45 yards by 24 yards
Step-by-step explanation:
You would have to first find out how many 2.5 increments are in each of the two lengths. Then multiply that number by 15
We have
and
so the equation is indeed exact. So we want to find a function such that
Integrating both sides of the first equation wrt gives
Differentiating both sides wrt gives
So we have
or
