How do i find length of third side in assembly language x$86.$ Here is my current code

; Calculate a$^2$ and store in xmm$3$

movsd xmm$3,$ xmm$15$

mulsd xmm$3,$ xmm$3$

; Calculate b$^2$ and store in xmm$4$

movsd xmm$4,$ xmm$12$

mulsd xmm$4,$ xmm$4$

; Add a$^2$ and b$^2,$ result in xmm$3$

addsd xmm$3,$ xmm$4$

; Calculate $2$ab and temporarily store in xmm$4$

movsd xmm$4,$ xmm$15$

mulsd xmm$4,$ xmm$12$

mulsd xmm$4,$ qword $[$two$]$ ; $[$two$]$ should contain the double $-$ precision floating $-$ point value of $2\mathrm{.}0$

; Calculate $2$ab $*$ cos$(\backslash$theta $)$ and store in xmm$4$

mulsd xmm$4,$ xmm$14$

; Subtract the product from the sum of squares

subsd xmm$3,$ xmm$4$

; Take the square root of xmm$3$ to get the length of the third side

sqrtsd xmm$0,$ xmm$3$ ; The result is now in xmm$0$

mov rax, $1$

mov rdi, length$\_$third$\_$side

call printf

; Output newline

mov rdi, newline

call printf

;Formula for third side: $c\frac{?}{S}=qrt(a^{{?}^{{?}^{?}}}2+b^{{?}^{{?}^{?}}}2-2ab**cos(t))$
