1st Angle = 45°
2nd angle = Right angle = 90°
Sum of Angles of Triangle= 180°
Let, 3rd angle = x
So, x + 45 + 90 = 180
x + 135 = 180
x = 180-135
x = 45°
Than, 3rd angle = 45°

Given that, one of the angle is 45°
so, let us take angle(BAC) = 45°
We know that, in a right angle triangle,
angle(ABC) = 90°
So,
angle(ABC) + angle(BAC) + angle(ACB) = 180°
[Sum of interior angles in a triangle is 180]
So,
45° + 90° + angle(ACB) = 180°
angle(ACB) = 180° - 135°
angle(ACB) = 45°
So,
the two angles are 90° and 45°
