-196 $^{\circ}$C -321 $^{\circ}$F
This question asks us to convert a measurement in Kelvin to both Celsius and Fahrenheit. To convert to Celsius, use the formula $^{\circ}$C=K-273 and to convert to Fahrenheit, use the formula $^{\circ}$F=1.8$\times$(K-273)+32. When you do this conversion with 77 K you get -196 $^{\circ}$C and -321 $^{\circ}$F
