Answer:
AE = 15 cm; ED = 18 cm; AD = 15 cm (given)
Step-by-step explanation:
ΔBEC ~ ΔAED so ...
AD/BC = AE/BE = (BE+AB)/BE = 1 + AB/BE
Substituting given numbers (lengths in centimeters), we have ...
15/10 = 1 + 5/BE
1/2 = 5/BE
BE = 10
Similarly, ...
1/2 = 6/CE
CE = 12
Then the unknown sides are ...
AE = AB + BE = 5 + 10 = 15 . . . cm
ED = CE + CD = 12 + 6 = 18 . . . cm
Answer:
84
Step-by-step explanation:
First, there are 6 pages of work. then multiply 6 by the number of questions (14)
6x14=84
1841 ≈ 1800 (nearest hundred)
964 ≈ 1000 (nearest hundred}
<span>1,841 + 964 </span>≈ 1800 + 1000 = 2800 (Answer B)
