Question

If an angle of a triangle are in the ratio 2:3:4. Find the value of each angle.

Answer 1

let the 3 angles be 2x, 3x, 4x respectively
we know that sum of all angles of a triangle is 180° .... therefore
2x + 3x + 4x = 180
9x = 180
x= 20
Substituting value of x in the sides...we get the angle 2×20, 3×20, 4×20
therefore the three angles are
40, 60 and 80 respectively

Hope it helps

Answer 2

If angle of a triangle are in the ratio 2:3:4

Let angle of triangle be 2x, 3x, 4x respectively

Then,

2x+3x+4x=180° ( sum of all angles of a triangle=180°)

9x=180°

x=180°/9

x=20°

So angle are,

2x=2×20°= 40°

3x=3×20°= 60°

4x=4×20°= 80°

Then angles are 40°,60°,80° respectively.
