Step-by-step explanation:
let measurements be =x
1st angle=3x
2nd=4x
3rd=11x
sum of all angles in triangle is 180°
so, 3x+4x+11x=180
18x=180
x=10
so, 1st angle=3×10=30°
2nd=4×10=40°
3rd=11×10=110°

Answer:
Scalene triangle
Explanation:
The triangle is called scalene because all of its sides are unequal.
Bonus (value of all angles):
Total sum of all angles of a triangle = 180°
Angle 1 = 3x
Angle 2 = 4x
Angle 3 = 11x
Sum of all angles = 3x + 4x + 11x
3x + 4x + 11x = 180°
18x = 180°
x = = 10
Angle 1 = 3 × 10 = 30°
Angle 2 = 4 × 10 = 40°
Angle 3 = 11 × 10 = 110°
