Answer:
I would use similar triangles
Step-by-step explanation:
There is no angle (apart from the right angle) given in the problem. so in order to find the side "x", in one step calculation, I would use similar triangles and the equation that comes from the proportion among the similar sides:

The interquartile range, IQR, is equal to the difference of Q1 and Q3 (first and third quartiles). These markers are visually shown as the edges of the box.
IQR = Q3 - Q1
IQR = 36 - 16
IQR = 20
Final Answer: Choice D) 20
