We can directly use scientific calculators by pressing the cosecant of the function followed by the measure of the angle. In the cases in which this function is absent, remember that cosecant is the reciprocal of the sin. Therefore, the above can also be expressed as 1/sin(40°), which gives an answer of 1.556. Therefore, the answer is the third option.
