All the angles in the diagram are measured to the nearest degree. Work out the upper bound and lower bound of angle x 59 degree 108 degree 81 degree X degree

lower bound, x = 110.5°

              upper bound, x = 113.5°

Step-by-step explanation:

There is no diagram but I am going to assume it is a quadrilateral since it has 4 angles. The sum of the angles of a quadrilateral is 360°.

           Upper       Lower

59°       58.5° ≤ a < 59.5

108°    107.5° ≤ b < 108.5°

81°       80.5° ≤ c < 81.5°  

Total:  246.6° ≤ x < 249.5°

Subtract the lower and upper bound totals from 360° :

                  360.0           360.0          

              -  246.5       - 249.5

x =              1 1 3.5           1 1 0.5
