In triangle ABC, angle B is obtuse. What are the other two angles?

The sum of all angles in a triangle is 180 degrees. If one of the corners is obtuse. An obtuse angle is the angle that is greater than 90 degrees. It turns out that if the sum of all the angles in the triangle is 180 degrees, and one of the angles is larger, which is 90 degrees, then 180 – 90 = 90 (this is the approximate sum for the remaining two angles). 90: 2 = 30 (this is the approximate value of each angle). It turns out that the two remaining corners are sharp.
