Question

the angle of a triangle are in ratio 1 2 3 find the meadure of all angle triangle ​

Answer 1

Answer :-

__________________________

Let the common ratio be x

Then , the angels of the triangle are x , 2x and 3x

Therefore ,

x + 2x + 3x = 180°

6x = 180°

x = 180° / 6

x = 30°

•°• The angels of the triangle are 30° , 60° and 90°

Answer 2

let angel A = X

angle B = 2X

angle C= 3X

in ∆ ABC ,

X+2X+3X=180° [ sum of all angles of ∆ is 180° ]

6X=180°

X=180°/6=30°

X=30°

angle A= X= 30°

angle B=2X=2×30°=60°

angle C=3X=3×30°=90°
