What’s the length of E to D
what’s the length of B to E

Given:

In triangle ACD, BE||CD, AB = 20 cm, BC = 5 cm, CD = 18 cm, AE = 26 cm.

To find:

(a) The length of ED.

(b) The length of BE.

Solution:

In triangle ABE and ACD,

BE||CD, so angle ABE and angles ACD are corresponding angles. So, their measure are equal.

         (Corresponding angles)

         (Common angle)

Now,

Corresponding sides of similar triangles are proportional.

(a)

Isolate AD.

Now,

Therefore, the length of ED is 6.5.

(b)

Multiply both sides by 18.

Therefore, the length of BE is 14.4.
