Webcos A = − cos ( 180 − A) e.g cos ( 120) = − c o s ( 180 − 120) = − cos 60 i.e − 1 / 2 or − 0.5. This could work if you knew the measure of angle A, but presumably that was not the … Web29 nov. 2024 · Answer: If a triangle does not have a specific mention of a right angle. Then, we can determine if a triangle is acute, right, or obtuse by using the converse Pythagorean theorem. As if the sum of the square of the two shortest sides of a triangle is greater than the square of the longest side.
