Yes. The temperature doesn't matter, ultraviolet light striking the skin causes tanning.
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.
cot 115 deg = - tan25 deg
It is: tan(52)*9 = 11.519 meters rounded to three decimal places
Tan 42 degrees = 0.9004
Tan(74 degrees) = 3.487414444.....
tan(52 deg) = 1.2799, approx.
tan(11o) = 0.19438 =======
52 degrees Fahrenheit = 11.1 degrees Celsius
A circle is 360 degrees. So:52% of 360 degrees:= 52% * 360= 0.52 * 360= 187.2 degrees
It is: 90-52 = 38 degrees
tan(22.5)=0.414213562
The answer is 0.2867.
