Question

If the angles of a triangle ABC are in the ratio 2 : 3:4, find the
measures of the angles A, B and C.​

Answer 1

Step-by-step explanation:

Let the ratio be x

2x+3x+4x = 180 ( Angle sum property)

9x=180

x = 180/9

x = 20

Angle A = 2 * 20 = 40

Angle B = 3 * 20 = 60

Angle C = 4 * 20 = 80

Answer 2

Answer:

sum of triangle =180

Let a = 2x

B = 3x

C = 4x

2x + 3x + 4x = 180

9x = 18o

x = 180 |9

x = 20

So a = 40

B = 60

And c= 80
