Question

The angles of a triangle are in the ratio 1 :2:3 prove that the triangle is right angled​

Answer 1

let the angle of the triangle be x°,2x°and 3x°:- according

x°+2x°+3x°=180°

6x°=180°

then, x will be 30°

then multiply 2×30=60°

3×30=90°

hence proved that it is a right angled triangle.

hope it will help u

Answer 2

$\huge\bold\red{SOLUTION}$$\bold\purple{♡FollowMe♡}$

Let the angles be 1x, 2x and 3x

x+2x+3x=180° [angle sum property of triangle]

6x = 180

x= 30

thus angles are 30°, 60°, 90°

Since 1 angle is 90° thus it is an right angled triangle.
