oh, yes people can get sunburnt or tan during weather near 45 degrees!
75 degrees Fahrenheit is 23.89 degrees Celsius.
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
outside temps above 100 degrees
Tan 42 degrees = 0.9004
Tan(74 degrees) = 3.487414444.....
Yes. The ability to tan has nothing to do with the temperature. But how strong the suns rays are. You can get a tan while its overcast for instance. (ie burnt face while snow skiing). If you can feel your skin warming up from the UV rays you will get a tan.
75 degrees Celsius
tan(11o) = 0.19438 =======
tan(22.5)=0.414213562
The answer is 0.2867.
148 degrees minus 75 degrees is 73 degrees
