Question

Angles of a triangle are in the ratio 1:2:3. Prove that the largest angle is a right angle.​

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.
