Question

If the angles of a triangle are in the ratio 2:3:4 find the measure of each angle

Answer 1

Step-by-step explanation:

$2 : 3 : 4 \\ \\ Let \: the \: unknown \: values \: be \: "x" \\ \\ 2x + 3x + 4x= 180°$

9x= 180°

X= 180/9

X = 20°

Substitution :

2x = 2×20 =40.

3x =3×20 =60.

4x =4×20=80.

Hope it helps.

Answer 2

Step-by-step explanation:

2x+3x+4x=180

9x=180

x=180÷9=20

2x= 2×20 =40

3x= 3×20 =60

4x=4×20=80
