You are competing in a race. The table shows the times from last year's race. You want your time to be last year's median time w
ith an absolute deviation of at most 4 minutes. Complete the inequality to represent the time (in minutes) you hope to achieve.
Race times (minutes)
26 35 27 32

36 40 38 32
To solve this we use trigonometric functions that would relate the hypotenuse y and the given values. For this case we use cosine function which is expressed as:
cosine theta = adjacent side / hypotenuse cosine 52 = 35 / y y = 35 / cos 52 y = 56.85
