You can put this solution on YOUR website! 30^2+X^2=34^6 THIS IS A RIGHT TRIANGLE WITH THE FORMULA FOR THE SIDES OF
A^2+B^2=C^2
30^2+X^2=34^2
900+X^2=1190
X^2=1190-900
X^2=290
X=SQRT290
X=17.03 FOR THE OTHER SIDE.
----------------------------------------------------------
SQRT.85~.92
---------------------------------------------------------
X=.04 OR X=4/100 OR X=4% OR X=1/25
----------------------------------------------------------
.0049=4.9*10^-3 BECAUSE WE HAVE MOVED THE DECIMAL 3 PLACES TO THE RIGHT OR WE'VE MULTIPLIED THE NUMBER BY 1,000
