First, we need to find the tangent values of the given angles:
tg(55°) = 1.428148006tg(35°) = 0.700207538tg(20°) = 0.363970234
Now we can substitute these values into the given expression:
(1.428148006 - 0.700207538) / 0.363970234
= 0.727940468 / 0.363970234
= 1.99999999
Therefore, the value of the expression is approximately 2.
