To find the secant of 10 degrees and 5 minutes (10°5'), first convert the angle to decimal form. 5 minutes is approximately 0.0833 degrees (since 5/60 = 0.0833). So, the angle is approximately 10.0833 degrees. Using a calculator to find sec(10.0833°), remembering that sec(x) = 1/cos(x), gives approximately 1.0157.
