Question

In AABC parallel line to BC intersect AB and AC at D and E. respectively then AD= 7.2, AB= 18.4, AE=5.4 then DB=______ EC=______ and AC= _____​

Answer 1

total length of ab 18.4 if ad is 7.2 then find DB to find DB we will subtract 7.2 from 18.4

18.4-7.2= 11.2

db is 11.2

the total length of ac is 18.2

ae is given 5.4 we have to subtract 5.4 from 18.4

18.4 - 5.4 = 13

Ae = 13

Answer 2

Step-by-step explanation:

AB = AD + DB

18.4 = 7.2 + DB

18.4 - 7.2 = DB

DB = 11.2

AD = AE

DB. EC

7.2 = 5.4

11.2 EC

7.2 /11.2 = 5.4/EC

9/1.4 = 5.4/EC

9 × EC = 5.4 × 1.4

9 × EC = 810

EC = 81.0 / 9

EC = 9.0

AC = AE + EC

AC = 5.4 + 9.0

AC = 14.4
