Question

one angle of a triangle is twice the third angle and second angle is thrice the third angle find three angles​

Answer 1

Answer:

The angles are 30°, 60° and 90°

Step-by-step explanation:

Let the third angle be x

The first one = 2x

And the second = 3x

So,

x + 2x + 3x = 180°  ∵Sum of angles of a Δ is 180°

6x = 180°

x = 30°

==============================

The first one = 2x = (2)(30) = 60°

The second = 3x = (3)(30) = 90°

And the third one = x = 30°

So the angles are 30°, 60° and 90°
