Question

If one angle of a triangle is60 and other two angles are in the ratio 1:2 find the angle

Answer 1

40 and 80 degrees respectively

60+x+2x=180

3x=120

x=40

2x=80

Answer 2

One angle of triangle is 60

Ratio is given of other two angels 1:2

Let one angle be x

Let other angle be 2x

Sum of all three angles of triangle is 180

60+2x + x =180

3x =120

x =40

Reasoning two angels are 40 and 80
