The fishing pole in the figure below makes an angle of $20\mathrm{.}0$ with the horizontal. What is the torque exerted by the fish about an axis perpendicular to the page and passing through the angler's hand if the fish pulls on the fishing line with a force

F $=104$ N

at an angle $37\mathrm{.}0$ below the horizontal? The force is applied at a point

L $=2\mathrm{.}20$ m

from the angler's hands. $($Enter the magnitude in N $$ m$,$ accurate to at least the nearest integer.$)$

A fisherman in a boat holding a fishing rod has a fish at the end of his line. The rod is of length L and he is holding it an angle of $20\mathrm{.}0$ above the horizontal. The fishing line, which extends from the end of the rod, makes an angle of $37\mathrm{.}0$ below the horizontal. A dotted line extends from the tip of the rod and makes an angle of $20\mathrm{.}0$ above the horizontal. An arrow labeled vector F points along the fishing line toward the fish.

What If$?$ To reel in the fish, the angler now pulls back on the fishing rod, increasing the angle it makes with the horizontal to $39\mathrm{.}5.$ If the fish still applies the same force in the same direction, what is the increase in the torque exerted by the fish about an axis perpendicular to the page and passing through the angler's hand? $($Enter the magnitude in N $$ m$.)$
