Final answer:
To find the value of n in the given expression, subtract the two given angles from 180°.
Step-by-step explanation:
To find the value of n in the given expression 131° n° 160°, we need to calculate the missing angle. Since we know that the sum of interior angles of a triangle is 180°, we can subtract the two given angles (131° and 160°) from 180° to find the missing angle.
Missing angle = 180° - (131° + 160°) = 180° - 291° = - 111°
Therefore, the value of n is -111°.
