Xto the second power = 500

what values can be used square roots only !

Option A is the correct answer.

Step-by-step explanation:

Obtuse angle mean angle means angle less than 180° and greater than 90°.

Bisector of 90° will create two 45° angles.

Bisector of 180° will create two 90° angles.

So bisector of an obtuse angle will make 2 angles in between 45° and 90°.

That is bisector of an obtuse angle will make 2 acute angles

Option A is the correct answer.
