Question

The angles of a triangle are in the ratio 2: 3: 4; the three angles are

• A. 40^o, 60^o, 80^o
• B. 70^o, 46^o, 64^o
• C. 80^o, 50^o, 50^o
• D. 60^o, 90^o, 30^o

Answer 1

The correct option is A

40^o, 60^o, 80^o

Let the angles of the given triangle measure 2x, 3x and 4x respectively.

By angle sum property,

2x + 3x + 4x = 180^o

x = 20^o

Therefore angles of the triangle are 40^o, 60^o and 80^o
