Question

Q.3 The angles of a triangle are in the ratio of 2:3:4 find the
measure of each one of the angles.
(4)​

Answer 1

Answer:

40°, 60° , 80°

Step-by-step explanation:

angles of triangle = 2x , 3x , 4x

Angle sum of triangle =180

2x+3x+4x=180

9x=180

x=20

2x=2×20=40°

3x= 3×20=60°

4x=4×20=80°

Answer 2

Answer:

$2x + 3x + 4x = 180 \\ 9x = 180 \\ \\ x = 20 \\ 2x = 2 \times 20 = 40 \\ 3x = 3 \times 20 = 60 \\ 4x = 4 \times 20 = 80$
