Final answer:
The cotangent of 37 degrees expressed as its cofunction is tan(π/3), matching option B, which is the tangent of its complementary angle in radians.
Step-by-step explanation:
The cotangent of 37 degrees can be expressed as the cofunction of its complement, which is 53 degrees (90 degrees - 37 degrees = 53 degrees). In radians, 53 degrees is approximately π/3 radians. The cofunction of cotangent is tangent. Therefore, the cotangent of 37 degrees expressed as its cofunction is tan(π/3), which corresponds to option B.
