sin PQR = 300/600 = 1/2
so
PQR = 30 degrees
that is 30 degrees south of west
or 60 degrees west of south
which id a compass bearing of
180 + 60
= 240 degrees clockwise from north
cos 30 = RQ/600
RQ = 520 m
so
PQR = 30 degrees
that is 30 degrees south of west
or 60 degrees west of south
which id a compass bearing of
180 + 60
= 240 degrees clockwise from north
cos 30 = RQ/600
RQ = 520 m
