Yeah if you stay in the sun for 3 hours
cot 115 deg = - tan25 deg
77% of 360 degrees is 277.2 degrees.
77 degrees Fahrenheit = 25 degrees Celsius
77 degrees Fahrenheit = 25 degrees Celsius
In a scalene triangle, all angles are different, and the sum of the angles must equal 180 degrees. If two angles are 63 degrees and 77 degrees, you can find the third angle by subtracting the sum of the known angles from 180 degrees: ( 180 - (63 + 77) = 180 - 140 = 40 ) degrees. Therefore, the angles of the scalene triangle are 63 degrees, 77 degrees, and 40 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.
77 degrees Celsius = 170.6 degrees Fahrenheit.
cot 115 deg = - tan25 deg
Tan 42 degrees = 0.9004
Tan(74 degrees) = 3.487414444.....
