Question

find the angles of triangle if they are in ratio2:3:4​

Answer 1

Hello!!!

$let \: the \: angles \: be \: 2x \: 3x \: and \: 4x \\ the \: sum \: of \: the \: angles \\ of \: triangle = 180 \\ so \\ 2x + 3x + 4x = 180 \\ 9x = 180 \\ x = 20 \\ 2x = 2 \times 20 = 40 \\ 3x = 3 \times 20 = 60 \\ 4x = 4 \times 60 = 240$

Hope it helps you.

Answer 2

Answer:

Sum of angles of triangle=180°

Ratio=2:3:4

Let the angles be = x

So.....

2x+3x+4x=180°

9x=180°

x=180÷9=20°

1st angle=2x=2×20°=40°

2nd angle=3x=3×20°=60°

3rd angle=4x=4×20°=80°
