The angles of triangle are in the ratio 2:3:4. Find the size of each angle.​

Answer 1

$we \: know \: that \\ sum \: of \: all \: angles \: of \: triangle \: is \: 180° \\ \\ let \: the \: angles \: be \: 2x \: 3x \: 4x \\ atq \\ 2x + 3x + 4x = 180° \\ = > 9x = 180° \\ = > x = \frac{180}{10} \\ = > x = 18 \\ \\ 2x = 2 \times 18 = 36° \\ 3x = 3 \times 18 = 54° \\ 5x = 54° \times 18 = 90°$

Answer 2

Answer:

40:60:80

Step-by-step explanation:

let size of angle be x

2x+3x+4x=180. as all triangle are equal to 180°.

9x=180

x=180/9

x=20

2x=2×20=40

3x=3×20=60

4x=4×20=80
