Question

the angles in the ratio of 2 : 3 :
4 forms a complete angle then the smallest angle​

Answer 1

Answer:

Step-by-step explanation:

Complete angle = 360°

So 2x+3x+4x =360

Hence 9x=360

So X=360/9=40

This is value of X

Now angles are 80,120&160

Answer 2

Answer:let common ratio be x

Then

Ratio- 2x:3x:4x

Sum of all angles =360

Therefore, 2x+3x+4x=360

X=40

Therefore, angles are 2*40, 3*40 & 4*40

I.e 80, 120 & 160

So, smallest angle is 2x
