Answer: Type : equilateral triangle
Angles : 60,60,60
Explanation:
Three angles of the triangle
= 1)x+40 2)2x+20 3)3x
Hence
x+40+2x+20+3x=180 ----------(sum of angles of triangle = 180)
6x+60=180
6x=120
x=20
hence
The angles are
1)20+40 = 60
2)40+20=60
3)3x=60
As all angles are 60 the triangle is equilateral triangle
