The angles of a triangle are in the ratio \(3: 5: 10\). Then the ratio of the smallest side to the greatest side is :

  1. A \(1: \sin 10^{\circ}\)
  2. B \(1: 2 \sin 10^{\circ}\)
  3. C \(1: \cos 10^{\circ}\)
  4. D \(1: 2 \cos 10^{\circ}\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(1: 2 \cos 10^{\circ}\)

Step-by-step Solution

Detailed explanation

Let the angles of a triangle are \(3 x, 5 x\) and \(10 x\). \(\therefore \quad 3 x+5 x+10 x=180^{\circ}\) \(\Rightarrow \quad x=10^{\circ}\) \(\therefore\) Smallest angle of a triangle \(=30^{\circ}\) and the greatest angle \(=100^{\circ}\) Required ratio…
