The correct answer is A.) Obtuse.
When an angle is over 90° it is considered an obtuse angle. Any angle that measures under 90 is an acute angle.
Answer:
127 degrees
Step-by-step explanation:
1. Find the angle next to "x" using the fact that all the angles in a triangle add to 180 degrees.
180-30-97 = 53
2. Angle X and the angle that is 53 degrees are supplementary meaning they will add to 180 degrees since it's on a line
180-53=57
Hope this helped :)
