Answer

ACUTE ANGLED TRIANGLE

angles of triangle in the ratio = 5:3:7

let, common ratio be x

therefore,

1st angle=5x

2nd angle=3x

3rd angle=7x

sum of all angles in a triangle = 180degrees

so, 5x+3x+7x = 180degrees

     15x = 180degrees

      x=180/15 = x = 12degrees

1st angle = 5x = 5×12 = 60degrees

2nd angle = 3x = 3×12 = 48degrees

3rd angle = 7x = 7×12 = 84degrees

here , all angles are less than 90degrees

so the triangle is acute angled triangle.
