WebBy using Thales Theorem, [As DE ∥ BC] AD/BD = AE/CE Let CE = x. So then, 6/9 = 8/x 6x = 72 cm x = 72/6 cm x = 12 cm ∴ AC = AE + CE = 12 + 8 = 20. ii) If AD/DB = 3/4 and AC = 15 cm, Find AE. Solution: Given: AD/BD = 3/4 and AC = 15 cm [As DE ∥ BC] Required to find AE. By using Thales Theorem, [As DE ∥ BC] AD/BD = AE/CE Let, AE = x, then CE = 15-x.

WebMar 19, 2024 · DE is parallel to BC . AE = 4 cm. AD = 3 cm. AC = 10 cm . Concept Used: AAA' similarity rule. If three angles of two triangles are equal then corresponding sides of similar triangles are proportional. Calculation: If DE is parallel to BC . ∠A = ∠A (Common) ∠ADE = ∠ABC (corresponding angles of parallel sides are equal) WebAnswer: Given, in ABC, DE∥BC. ∴ AD/DB = AE/EC (Using Basic proportionality theorem) ⇒1.5/3 = 1/EC. ⇒EC = 3/1.5. EC = 3×10/15 = 2 cm. Hence, EC = 2 cm. herdy online shop
