If the angles of a triangle are in the ratio 4: 1: 1 , then the ratio of the longest side to its perimeter is
Options
- A3 :(2+ 3 )
- B2:(1+ 3 )
- C1:(2+ 3 )
- D2: 3
Correct answer
A. 3 :(2+ 3 )
Step-by-step solution
Let the angles of the triangle be 4 x, x and x . aligned & 4 x+x+x=180^ 6 x=180^ x=30^ & 120^ a = 30^ b = 30^ c & a :( a + b + c ) & = ( 120^ ): ( 120^ + 30^ + 30^ ) & = 3 2 : 3 +2 2 = 3 :( 3 +2) aligned
