answer correctly as mentioned above and I will surely follow you​

Answer 1

Step-by-step explanation:

let the angles be x, 2x and 3x

x+2x+3x=180°

6x=180°

x=30°

largest angle is 90°

please mark as brainliest

Answer 2

Answer:

C

Step-by-step explanation:

Add the ratios

$1+2+3=6$

The largest angle is represented by the highest ratio.

So to get measure of the angle it would the ratio over total of ration multiplied by 180°(The sum of all angle of a triangle)

$\frac{3}{6}*180= 90$°
