Answer:
lower bound is 110.503 and upper bound is 112.500
Step-by-step explanation:
Given 3 angles around a point we are to find the fourth angle.
The three angles are 59. 108 and 81.
They are rounded off to the nearest degrees.
As per this given, fourth angle = 360-(59+108+81) = 112 degrees
Since angles were rounded off, the extreme chances are
58.5, 107.5, and 80.5 rounded off to 59, 108, and 81 from left side.
Right side maximum is 59.499, 108.499, 81.499 (taken upto 3 decimals) rounded to 59, 108, 81
In the first case, fourth angle would be 112.50 and in the second case, the fourth angle would be 110.503 degrees
Thus lower bound is 110.503 and upper bound is 112.500
