Congruent sides pair with each other. AB is congruent to FG, so put FG (x) under or below 16 (it doesn't matter as long as FH is next to it). Cross multiply, then continue as if it's an equation. With that, you get the answer that x, or FG, equals 9 m.

T = 12 min, T o = 80° C, T s = 50 °C, T ( 12 ) = 60° C
60 = 50 + ( 80 - 50 ) · e^(-12k)
10 = 30 · e^(-12k)
e^(-12k) = 0.3333...
ln ( 0.333.. ) = - 12 k
- 12 k = - 1.1
k = ( - 1.1 ) : ( - 12 ) = 0.0916
Answer: D ) 0.0916
