We know that tanθ = sinθ/cosθ
For a number to be undefined, the denominator must equal to 0. At π/2, the cosθ value is 0 and sinθ is 1. Hence, tan(π/2) is undefined.
Hope I helped :)

Answer:
6B = F8
Step-by-step explanation:
The correct answer is A. The commutative property says that we can swap number when we add. More exactly... it means that a+b=b+a => -13+27=27+(-13)= 14
