Answer:

40.87 (Rounded to nearest hundredth)

Make sure you have the law of sines near by.

We have this for us:

sin48/x=sin90/55

xsin90=55sin48

x=55sin48/sin90 *To get our answer go on a calculator and type in 55×48 sin then take that number and divide it by 90 sin, then you will get your answer which is 40.87 rounded*
