Question

If the angle of triangle are in ratio 2:3:4 the largest angle will be ​

Answer 1

Answer:

Step-by-step explanation:

2x + 3x+ 4x=180°

=9x=180°

=x=20°

largest angle 4x=4(20)=80°

Answer 2

Answer:

80°

Step-by-step explanation:

$2x + 3x + 4x = 180 \\ 9x = 180 \\ x = 20 \\ 4x = 4 \times 20 = 80$
