Detailed Solution

It is given that the angles of a triangle are in the ratio

2 : 3 : 4

.
Let’s assume

x : y : z = 2 : 3 : 4

.
Then,

x = 2 t, y = 3 t

and

z = 4 t

.
We know, by angle sum property, the sum of all angles of a triangles is

180^{0}

⟹

2 t + 3 t + 4 t = 180^{o}

⟹

9 t = 180^{o}

⟹

t = 20^{o}

Hence,

x = 2 \times 20^{o}

⟹ x = 40^{o}

y = 3 \times 1 20^{o}

⟹ y = 60^{o}

z = 4 \times 20^{o}

⟹ z = 80^{o}

Thus, the values of the angles are

40^{o}, 60^{o}, 80^{o}

.
Therefore, option

3

is correct.
