Solution 1

The statement is sometimes true. In an isosceles right triangle, the two acute angles are not always equal. One angle is always 45 degrees, while the other is 90 degrees minus the first angle. Therefore, the cosine of the two angles will be equal only when the two angles are equal, which is when the Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
