Step-by-step explanation:
<u>Step 1: List out all of the formulas for the trigonometric functions
</u>
<em>sin(x) </em>= opposite/hypotenuse
<em>cos(x) </em>= adjacent/hypotenuse
<em>tan(x)</em> = opposite/adjacent
<u>Step 2: Find the value of h
</u>
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
