I have a triangle that adds up to 180 but the answers rhat it gives is acute, obtuse and right

  classification is based on the measure of the largest angle

Step-by-step explanation:

Every triangle will have angle measures that add up to 180°. The classification as to acute, right, or obtuse is based on the largest angle.

__

If the largest angle is less than 90°, the triangle is acute.

If the largest angle is equal to 90°, the triangle is right.

If the largest angle is greater than 90°, the triangle is obtuse.

__

Because you know the angle sum is always 180°, you can generally figure out what kind of triangle it is from the sum of two of the angles. If both are less than 90° and their sum is more than 90°, then the triangle will be acute, for example.
