Answer 2

Given

One angle of a right angled triangle is 30°

To Find

Other two angles of the triangle

Answer and explanation

Since the triangle is right angled triangle

Thus second angle = 90°

So

Sum all 3 angles = 180°

1st angle + 2nd angle + 3rd angle. = 180°

30° + 90° + 3rd angle = 180°

120° + 3rd angle = 180°

3rd angle = 180° - 120° = 60°

Thus angles are 30° , 90° and 60°.
