Question

THE THREE ANGLES OF A TRIANGLE ARE IN THE RATIO OF 2:3:4 . FIND THE MEASURE OF EACH ANGLE

Answer 1

Let all angle be 2x, 3x, 4x

180°=2x + 3x +4x
180°=9x
X = 20

Put the value of x in 3x, 2x and 4x

Answer 2

$2x + 3x + 4x = 180 \\ 9x = 180 \\ x = \frac{180}{9} \\ x = 20degree \\ each \: angle \: is \: 20 \: degrees$
