Find the value of the csc 40° using your calculator.

(a)1.342
(b)0.745
(c)1.556
(d)0.643

The answer is:

C. 1.556.

To solve the problem using our calculator we need to set it to "Degree" mode in order to avoid miscalculations.

Also, we need to remember that the cosecant (csc) is the inverse function of the sine, so:

Hence, the answer is C. 1.556.

Have a nice day!

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
