Which proportion is equivalent to a/b = c/d

PilotLPTM [1.2K]

The proportion equal to a/b = c/d is A.) A/C = B/D

We will know if a proportion is equivalent when its cross products are equal.

a/b = c/d where ad = bc

since ad = bc, a/c = b/d

The diagonals of a parallelogram are 24 meters and 40 meters and

Naddika [18.5K]

Answer:

28 m

Step-by-step explanation:

The longer side can be found using the Law of Cosines. The semi-diagonals are of length 12 and 20 m, and the angle between them facing the long side is 180° -60° = 120°.

c^2 = a^2 +b^2 -2ab·cos(C)

c^2 = 12^2 +20^2 -2·12·20·cos(120°) = 144 +400 +240 = 784

c = √784 = 28

The longer side is 28 meters.
