Answer 2

$\huge\bigstar\blue{Answer}$

Given :-

• angles of a triangle in ratio 1:2:3

To Find :-

• angles of the triangle

__________________________

Put x in the ratio

then,

x + 2x + 3x = 180

= = > 6x = 180

= = > x = 30

= = > 2x = 60

= = > 3x = 90

Hence angles of the triangle are 30° , 60° , 90°
