Solve for X.

should be a decimal.

The distance from the surfer to the shoreline will be found as follows:

tan theta= opposite/adjacent

theta =10°

opposite=7ft

adjacent= x ft

substituting the values in our formula and solving

for x we get

tan 10=7/x

hence

x=7/tan10

x=39.69897 39.7 ft

The surfer is 39.7 ft from the shoreline.
