Question 765022
An acute angle θ is in a right triangle with cos θ = five sixths (5/6). What is the value of sec θ?
<pre>
Since the secant is the reciprocal of the cosine, which is {{{5/6}}},
the secant is its reciprocal, {{{6/5}}}.

No need to draw a triangle or use the Pythagorean theorem on this one.
