55°

Answer 1

In a right triangle, one of the angles is always 90° by definition because it is a right angle. The sum of the angles in any triangle must equal 180°. If one angle is 55° and another is 90°, we can find the third angle by subtracting the sum of these two angles from 180°.

Let's calculate the measure of the third angle:

180° - 90° - 55° = 35°

So, the measure of the third angle in the triangle is 35 degrees.
