Answer 2

plz help only have 3 mins left!!

Answer 3

I got that backwards

Answer 4

use cos law
C^2=A^2+B^2-2AB cos(c)

Answer 5

use cosine rule
\[f^{2}=d^{2}+e^{2}-2decos(F)\]
where F is the angle you are working out

f is the side length f d and e are side lengths

f is opposite angle F

Answer 6

what numbers do i plug in??

Answer 7

f=3.1
d=2
e=1.8

Answer 8

side lengths are opposite their angle

Answer 9

cos (m)=[C^2-A^2-B^2]/-2AB
