I would estimate 643 - 189 by rounding 643 to the tens place and 189 to the hundreds place.
643 => 640
189 => 200
Now you can subtract 200 from 640.
640 - 200 = 440
Hi Vance :)
a=leg unknow
b=leg
c=hypotenuse
a²+b²=c²
a²=c²-b²
a²=145² - 144²
a²=21,025 - 20,736
a²=289
a=√289
a=17
unknow leg = 17 units
