Yes because they add up to 180 degrees
The cotangent function is the reciprocal of the tangent function, so cot(115 degrees) is equivalent to 1/tan(115 degrees). Since tan(115 degrees) is equivalent to -tan(65 degrees) due to the periodicity of the tangent function, cot(115 degrees) simplifies to -tan(65 degrees), which corresponds to option A.
180 degrees C = 356 degrees F.
200 degrees Celsius is 392 degrees Fahrenheit.
