Helpppppppppppppppppppppp!!!!!!! Plzzzzzzzzzzzzzzz
diamong [38]

Step-by-step explanation:

The sum of the interior angles of a triangle is equal to 180° so we can write

y + 2y + 3y = 180° \Rightarrow 6y = 180°

Solving for y, we get

y = 30°

So the other two angles of the triangle are

2y = 2(30°) = 60°

and

3y = 3(30°) =90°
