What is the length of the side f? We have a triangle with sides d,e,f and angles D,E,F (D,d) = (36`^@` ,62) (E,e) = (42`^@` ,71) (F,f) = (102`^@` ,f)

Using the sine rule

`sinF/(f) = sinD/d = sinE/e = sin(36)/62 = 0.0095`

`therefore` `f = sinF/0.0095 = sin102/0.0095 = 103.0`

The length of f is 103.0
