Question

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

Answer 1

80 degrees.

180 degrees - 60 degrees = 120 degrees

3 units = 120 degrees

1 unit = 120 degrees ÷ 3 units = 40 degrees (one angle)

2 unit = 40 degrees x 2 = 80 degrees (another angle)

80 / 60 / 40

80 is greater than 60 and 40, so the largest angle is 80 degrees.
