Question

the angels of a triangle is 3:1:2 which is the largest angle​

Answer 1

Answer:

let the unknown value be x

3x+1x+2x=180°(angle sum property)

6x=180°

x=180/6

x=30

So the angles are:

3x=3*30=90°

1x=1*30=30°

2x=2*30=60°

The largest angle is 90°

Answer 2

Answer:

90 degree

Step-by-step explanation:

the 3 angles are in a ratio = 3:1:2

sum of all 3 angles is = 180

so,

let the unknown value be x

3x + 1x + 2x = 180

6x = 180

x = 180/6

x = 30

the angles are -

3x = 3*30 = 90

1x = 1*30 = 30

2x = 2*30 = 60

the highest angle is 90 degree
