How i solved it /: A^2+9^2=15^2 A^2+18=225 225-18=207 207=a^2

OpenStudy (xguardians):

15^2 = 9^2 + x^2

OpenStudy (calculusxy):

9^2 = 81 not 18

OpenStudy (xguardians):

9^2 = 81 not 18

OpenStudy (faiqraees):

9^2 =81 not 18

OpenStudy (xguardians):

hahaha

OpenStudy (calculusxy):

that was very ironic :)

alones (alones):

LOL I guess another mistake in my second step x[

OpenStudy (xguardians):

xD, always check over your work.

alones (alones):

Okay here A^2+9^2=15^2 A^2+81=225 225-81=144 144=a^2 and now do i divide by 2?

OpenStudy (calculusxy):

you need to find the square root of 144.

OpenStudy (calculusxy):

remember that the inverse of squares is the square root :)

alones (alones):
