Question

Can anyone help me for this question​

Answer 1

Answer:

x°+2x°+3x°=180°

6x°=180°

x= 30°

The angles are = 30°, 60°, 90°

As one of the angles is 90° hence it is Right Angle.

Answer 2

Answer:

It is a right angled triangle

Step-by-step explanation:

We do this by interior angle sum property

$x + 2x + 3x = 180\\3x + 3x = 180\\6x = 180 \\x =\frac{180}{6}\\x = 30$

Now, we find each angle and if one of them is 90° then it is a right-angled triangle

Angle 1 = 1 x 30 = 30

Angle 2 = 2 x 30 = 60

Angle 3 = 3 x 30 = 90

∴ It is a right angled triangle
