If a right triangle has an angle that is 55°. What is the measure of the third angle in the triangle A 180° b 55° c 35° or D 90°
The sum of the three angles in any triangle is always 180°. Since we know that one angle is 90° (right angle) and another angle is 55°, we can subtract these angles from 180° to find the measure of the third angle.
Third angle = 180° - 90° - 55° = 35°
Therefore, the measure of the third angle in the triangle is 35°.
The correct answer is C) 35°.
