(ii) The angles of a triangle are in the ratio 2 : 3:4. Find the angles.​

Answer 1

Answer:

let be the angles be. 1x,1x and 3x so here it is clear that 1x and and 1x are same so it is clear it is the property of isosceles triangle

the angles are in ratio 2x 3x 4x then their sum=180 degree

8x=180

x=180/8

then you put the x value then you will get the answer2x 3x 4x ok
