\pink{Answer}

  • The measure of ∆a = 2x
  • The measure of ∆b = 3x
  • The measure of ∆c = 4x


\\ \sf\longmapsto2x + 3x + 4x = 180 \\


\\ \sf\longmapsto9x = 180 = > x = 20


\\ \sf\longmapsto \: a = 2x = 2 * 2 0 = 4 0


\\ \sf\longmapsto \: b \: = 3x = 3 * 20 = 60


\\ \sf\longmapsto \: c = 4x = 4 * 20 = 80

hence , angles of the triangle are 40 , 60 and 80

Question:-

The angles of a triangle are in the ratio 2 : 3 : 4 . find the angles of the triangle .

Answer:-

40° , 60° and 80°

Step-by-step explanation:-

We know that sum of all the angles of a triangle adds to 180° .

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

Now,

=> 2x + 3x + 4x = 180°

=> 9x = 180°

=> x = 180/9

=> x = 20°

(The value of x is 20)

  • 2x = 2 × 20 = 40°
  • 3x = 3 × 20 = 60°
  • 4x = 4 × 20 = 80°
