Answer:

BC < ED ⇒ answer A

Explanation:

* Lets revise some facts in the triangle

- If one side of a triangle is longer than another side, then the angle

opposite the longer side will be larger than the angle opposite the

shorter side

- If one angle in a triangle is larger than another angle in a triangle,

then the side opposite the larger angle will be longer than the side

opposite the smaller angle

* Lets solve the problem

- In the two triangles BCD and DEB

∵ CD = 8 and BE = 8

∴ CD = BE

∵ Side BD is a common side in the two triangles

- The third side in Δ BCD is BC and the third side in DEB is DE

∵ BC is the opposite side to the angle of measure 24°

∵ ED is the opposite side to the angle of measure 30°

∵ The measure 24° < the measure 30°

∴ The side opposite to the angle of measure 24° < the side opposite

to the angle of measure 30°

∵ The other two sides of the 2 triangles BCD and DEB are equal

∴ We can compare between the 3rd sides in the Δ BCD and Δ DEB

∴ BC < ED
