Angles in a triangle must add up to 180°, so you could use this information to find the values of the angles. 1 + 2 + 2 = 5, 180 ÷ 5 = 36. 36 × 2 = 72, so 36 + 72 + 72 = 180. This means that the answer is A. acute, because all of the angles are below 90°. I hope this helps!

The triangle is acute angle triangle.

What is angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Let the common ratio be x

So,

Angles are x, 2x, 2x.

Using Angle Sum property, we have

x+2x+2x= 180

5x=180

x= 36

Thus the angles are 36, 72 and 72.

As, all the angles are acute angle.

Hence, the triangle is acute angled triangle.
