Question

measures of angles of a triangle are x,2x,3x what type of triangle is it?

Answer 1

Let∠A=x. ∠B=2x and ∠C=3x.
∠A+∠B+∠C=180° (Angle sum property of triangle)
x+2x+3x=180°
6x=180°
x=30°
Therefore,
∠A=30°
∠B=60°
∠C=90°
The triangle is right angled triangle because one angle measures 90°.

Answer 2

let x=∠1

2x=∠2 and

3x=∠3.

∵we know that sum of all the angles of a triangle =180°

∴∠1+∠2+∠3=180°

⇒x+2x+3x=180°

⇒6x=180°

⇒x=180/6

⇒x=30°

∴x=30° , 2x=60° and 3x = 90°.

∵it has 90° angle it is a right angle triangle.
