Answer 2

D and E are to points on the sides AB and AC of ΔABC, respectively. Such that DE || BC, thenRead more on Sarthaks.com - https://www.sarthaks.com/759290/d-and-e-are-to-points-on-the-sides-ab-and-ac-of-abc-respectively-such-that-de-bc-then

(i) In AD = 6 cm, DB = 9 cm and AE = 8 cm then find AC.

(ii) If AD/BD = 4/13 and AC = 20.4 cm. Then find EC.

(iii) AD/BD = 7/4 and AE = 6.3 cm then find AC.Read more on Sarthaks.com - https://www.sarthaks.com/759290/d-and-e-are-to-points-on-the-sides-ab-and-ac-of-abc-respectively-such-that-de-bc-then

(iv) In AD = 4x – 3, AE = 8x – 7, BD = 3x – 1 and CE = 5x – 3 then find x.Read more on Sarthaks.com - https://www.sarthaks.com/759290/d-and-e-are-to-points-on-the-sides-ab-and-ac-of-abc-respectively-such-that-de-bc-then
