Triangle ABC,DE paralal To BC, AD/DB=3/4,If BC/DE=?
Answers
Given:
In ΔABC,
DE // BC
To find:
Solution:
In Δ ADE and ΔABC, we have
∠A = ∠A ....... [common angle]
∠ADE = ABC ....... [corresponding angles since DE // BC (given)]
∴ Δ ADE ~ ΔABC ..... [by AA Similarity]
We know that the corresponding sides of two similar triangles are proportional to each other.
∴
⇒
substituting AD = 3 and DB = 4
⇒
⇒
⇒
Thus, the final answer is
