Question

if the angle<A,<B and <C of a triangle ABC are in the ratio 1:2:3, find them. what sort of a triangle is this​

Answer 1

Answer:

let the angles of the ΔABC=x, 2x and 3x

by angle sum property of triangle,

sum of all angles of a triangle=180°

∠A+∠B+∠C=180°

x+2x+3x=180°

6x=180°⇒x=30°

⇒∠A=30°

⇒∠B=2×30°=60°

⇒∠C=3×30°=90°

∵One angle of the ΔABC is 90° the triangle is a right angled triangle
