Step-by-step explanation:
Step 1: List out all of the formulas for the trigonometric functions
sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent
Step 2: Find the value of h
cos(68) = 13/unknown is FALSE
cot(68) = 13/h is FALSE
sin(68) = h/unknown is FALSE
tan(68) = h/13 is TRUE
Answer: The correct option would be D
