The 54 percentage of 40 inches is 21.6 inches
Y^2 + z^2=x^2
In a right triangle the sum of the sides^2 are equal to the hypotenuse^2
add 12.7 on both sides. i chose the bigger number to get rid of negatives
-3.6b + 5.5 = 6.1b
get b by itself by adding 3.6b to both sides
5.5 = 9.7b
the answer would be 5.5/9.7 = b
you can simply if need 0.567=b
Solutions: x=3 , y=5 , z=2
x+y+z=10
2x-5y+2z=-15
4x+y-z=15
