Quick! if bc is parallel to de, then all of the following are equivalent to each other

Option 3 is correct.

Step-by-step explanation:

Given ΔABC~ΔADE

If BC||DE, then we have to tell that which option is not equivalent.

If two triangles are similar then the corresponding sides of two triangles are in same proportion.

⇒

CE side is not the part of any of triangle ABC and ADE which includes in option 3.

Hence, is not equivalent to rest three fraction.

Option 3 is correct.

Step-by-step explanation:

∠4 = ∠1 & ∠2 = ∠3

360 - 2(98) = ∠2 + ∠3

∠3 = 164/2

∠3 = 82°
