Answer 2

As shown in picture:

Original x = 360 - (59 + 108 + 81) = 112 deg

Upper bound of x (when all known elements are considered at lower bound)

U = 360 - (58 + 107 + 80) = 115 deg

Lower bound of x (when all known elements are considered at upper bound)

L = 360 - (60 + 109 + 82) = 109 deg

Hope this helps!
