Question

Angle are in ratio 1:2:3: find is angle of triangle

Answer 1

Answer:

let the angles be x, 2x, 3x

sum of all the angles of a triangle is 180

btp,

x+2x+3x=180

6x=180

x=30

so all the angles are 30,60,90

Answer 2

Answer:

let the angles are 1x ,2x and 3x

so the dum of all angles of a triangle is 180°

so 1x +2x+3x=180°

= 6x=180°

= x = 180/6

= x= 30°

hence the first angle is 30° , second angle is 60° and third angle is 90°.
