Recall that in a right triangle, one of the angles is always 90° by definition.
The sum of the interior angles in any triangle is always 180°, so the other two angles must add up to 90°.
Given that angle B is stated as 152°, check if this is possible in a right triangle by comparing it to the 90° right angle and the total 180° sum.
Since 152° is greater than 90°, it cannot be one of the angles in a right triangle because the right angle already takes 90°, leaving only 90° for the other two angles combined.
Therefore, conclude that having an angle of 152° in a right triangle is impossible, making the statements about angles C and A incorrect.
