Answer:
13/84
Step-by-step explanation:
The relevant trig ratio is ...
Tan = Opposite/Adjacent
tan(H) = GI/HI
tan(H) = 13/84
The length of the midsegment of an isosceles trapezoid is the sum of the two bases, divided by 2. So this means -
(base 1+base2) / 2
(12+20) / 2
32/2
Length of midsegment = 16
