Ok, so we do pythagoran theorm so
assume that jason is to the left or right of the anchor
ok
the boat anchor is 172.22 feet so 20 feet above that is 152.22 feet
then the other leg or distance to jeff is 188.82
a²+b²=c²
152.22²+188.82²=c²
23170.9284+35652.9924=c²
58823.9208=c²
sqrt both sides
242.53643190251=c
the distance is about 242.5ft
