Question

In a triangle the angles are in the ration of 1:2:3 find the measure of each angle.​

Answer 1

Answer:

Let 1st angle =X

let 2nd angle 2x

let third angle=3x

sum of all angles of triangle=180

X+2x+3x=180

6x=180

X=30

1st angle=30

2nd angle=2*30=60

3rd angle=3*30=90

Answer 2

let the unknown three angles be x , 2 x and 3 x

angles of the triangles sum up to 180 °

x + 2 x + 3 x = 180 °

6 x = 180

x = 180 / 6

x = 30°

2 x = 2× 30 = 60°

3 x = 3 × 30 = 90°

therefore the three angles are 30 ° , 60° and 90° and it's a right angled triangle....

hope it helps !!
