Final answer:
The co-function of sec 35° 26' is (c) (cot 35° 26').
Step-by-step explanation:
The co-function of sec 35° 26' is (c) (cot 35° 26').
The secant function is the reciprocal of the cosine function, so the co-function of sec 35° 26' is the cotangent function.
The cotangent function is defined as the ratio of the adjacent side to the opposite side in a right triangle. It can be calculated using the formula cot(x) = cos(x)/sin(x).
In this case, since we are dealing with an angle of 35° 26', we can use trigonometric identities to find the value of cos 35° 26' and sin 35° 26'. Once we have those values, we can calculate cot 35° 26'.
