Answer:

Step-by-step explanation:

We know that the sum of angles in a triangle is 180 ( angle sum property)

x + 40 + 2x + 20 + 3x = 180

6x + 60 = 180

6x = 180 - 60, 6x = 120

x = 120/6 = 20

x = 20, 2x + 20 = 2(20) + 20 = 40 + 20 = 60

3x = 3(20) = 60

x + 40 = 20 + 40 = 60

It is an equilateral triangle as all angles are equal to 60.
