Answer»

AnSwEr :

Let the measures of angles of triangle = 5x , 6x and 7x .

The SUM of the angles of triangle = 180°

A.T.Q :

5x + 6x + 7x = 180°

18x                = 180°

x                   = 180 ÷ 18

x                   = 10

5x  =  5 × 10 = 50°

6x  = 6 × 10 = 60°

7x   = 7 × 10 = 70°

The SMALLEST angle = 50°
