Question

If one angle of a triangle is 60 degree and other two angles are in the ratio 1 :2, then the largest angle is

Answer 1

Answer:

let the angles be 1x & 2x

60+1x+2x=180°

3x=180-60

3x=120x

x=120/3=40°

the angles are 60,40,80

largest angle is 80°

Answer 2

Answer:80

Step-by-step explanation:

given one angle=60

Let other be x and 2x

So,

x+2x+60=180

X=40

So angles are. ....40,60 and 80

Largest angle=80
