Question

the hypotenuse is 10 and one leg is 9 what is the other leg?

Answer 1

asq+bsq=csq
asq+9sq=10sq
asq+81=100
asq=19
sqrta=sqrt19
a=about 4.36
I hope you can understand what I was trying to type! :-)

Answer 2

you can use the Pythagorean theorem a^2+b^2=c^2

so a^2+9^2=10^2

a^2+81=100

a^2-81=100-81

a^2=19

then you square root that and your answer is 4.358
