Question

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. 1 : 2 sin 10°

  2. 1 : sin 10°

  3. 1 : cos 10°

  4. 1 : 2 cos 10°


Solution

The correct option is D

1 : 2 cos 10°


Let the angles of a triangle are 3x, 5x and 10x.3x+5x+10x=1800x=100Smallest angle of a triangle=300 and the greatest angle =1000Required ratio=sin300:sin1000=1/2:cos100=1:2cos100
