Question

if the angles of a triangle are in the ratio of 2:3:4 ,find all the three triangles

Answer 1

Answer:

40 degrees 60 degrees 80 degrees

Step-by-step explanation:

2x+3x+4x = 180             (angle sum property)

9x= 180

x = 20

1st angle = 20 *2  2nd angle = 20*3 3rd angle = 20*4

hope it helps

Answer 2

Answer: The angles are 40° , 60° and 80°

Step-by-step explanation:

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

2x + 3x + 4x = 180 [Angle sum property of triangle]

9x = 180

x = 180/9

x = 20°

So,

2x = 2×20 = 40°

3x = 3×20 = 60°

4x = 4×20 = 80°
