Question
Solution 1
The given question is about the properties of a triangle. In a triangle, the sum of all angles is 180 degrees. If angle A is obtuse, it means it is greater than 90 degrees. Let's assume angle A = 90 + x (where x is the acute angle).
So, the sum of angles B and C would be 90 - x (since the sum of al Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
