Use a calculator to find the approximate value of sin-1 (0.549)

33.30°

Step-by-step explanation:First, make sure your calculator is in DEG

Then press shift and then sin, then insert your number 0.549 and then press the equality sign(=)

You will have the answer 33.3 approximately.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

so, converting firstly the mixed fractions to improper fractions and then "adding".
