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)
<u><em>Answer:</em></u>
The height of the stack = in
<u><em>Explanation:</em></u>
We are given that Jean stacks a dictionary on top of a novel.
This means that the total height of the stack will be equal to the height of the dictionary added to the height of the novel.
<u>From the givens, we have:</u>
height of dictionary = in
height of novel = in
<u>Now, adding the two height, we will have:</u>
Total height of stack = height of novel + height of dictionary
Total height of stack = in
Hope this helps :)
