Question

problem 4 angle a in triangle abc is obtuse. can angle b or angle c be obtuse? yes no

Explanation:

The sum of the interior angles of a triangle is 180 degrees. An obtuse angle is greater than 90 degrees. If angle A is obtuse (greater than 90 degrees), then the sum of angles B and C must be less than 90 degrees (since A + B + C = 180°). So neither angle B nor angle C can be obtuse.

Answer:

No
