Answer 1

Answer:

Step-by-step explanation:

A triangle has 3 angles.

They all add up to 180.

Now, so there are 2 cases.

1st  triangle has angles x°,x°,4x° ,

And ,

x°,4x°,4x° ,

Solving both ,

x+4x+4x=9x=180;x=20 ,

x+4x+4x=9x=180;x=20 ,

So, angles will be 20,80,80 ,

And ,

4x+x+x=6x=180;x=30 ,

4x+x+x=6x=180;x=30 ,

So, angles are 30,30,120.

Hope it helps you.
