Answer 1

Answer:90°

Step-by-step explanation:

According to angle sum property sum of 3angles of a triangle is equal to 180°...

So,

1:2:3=180°

Let,

1 be 1x; 2 be 2x; 3 be 3x

Then,

1x+2x+3x=180°

6x=180°

x=180/6

x=30°

Now,

1x=30

2x=2×30=60°

3x=3×30=90°

Therefore, largest angle is 90°

Hope this helps uu...

Thanks for points..
