Question

Q.1) Three angles of a triangle are in the ratio of 3:4:2. Find the measure of each angle?
​

Answer 1

Step-by-step explanation:

Let Triangle be ABC

AND A:B:C is 3:4:2 ATQ

as the sum of all angles of a triangle is 180

then Angle A + Angle B + Angle C = 180

3x + 4x + 2x = 180

9x = 180

x = 20

Angle A = 3 X 20 = 60

Angle B = 4 X 20 = 80

Angle C =  2 X 20 = 40

Answer 2

Answer:

let the angles be 3x, 4x and 2x

solution:

3x+4x+2x= 180° (angle sum property of a triangle)

9x=180°

=>x=180/9

x =20

=>3x= 3×20=60°

4x= 4×20=80°

2x= 2×20=40°

Therefore, the angle measure of a triangle in the ratio of 3:4:2= 60°, 80° and 40°
