Given information:
- Angle A = Angle B + Angle C
- Angle B : Angle C = 2 : 3

Solution:

Step 1: Expressing angles in terms of variables
Let's assume:
Angle B = 2x
Angle C = 3x

Step 2: Using the first given information
According to the first given information:
Angle A = Angle B + Angle C
A = 2x + 3x
A = 5x

Step 3: Sum of angles in a triangle
The sum of angles in a triangle is 180 degrees.
Therefore:
A + B + C = 180
5x + 2x + 3x = 180
10x = 180
x = 18

Step 4: Calculating the angles
Now, substitute the value of x back into the expressions for angles B and C:
Angle B = 2x = 2 * 18 = 36 degrees
Angle C = 3x = 3 * 18 = 54 degrees
Angle A = 5x = 5 * 18 = 90 degrees

Conclusion:
The three angles of the triangle ABC are:
Angle A = 90 degrees
Angle B = 36 degrees
Angle C = 54 degrees
