All the angles of a triangle add up to 180 degrees.

So,

x+4x+4x= 180

Combine like terms.

9x= 180

Divide by 9 into both sides.

x=20

Now, plug those in for the measures of the angles.

4(20)= 80

The angles measures are 80,80, and 20.

We can check it by seeing if it adds up to 180.

80+80+20= 180

This works.

I hope this helps!
