Which equation correctly applies the law of cosines to solve
for an unknown angle measure?
72 = 82 + 112 – 2/8)(11) cos(n)
82 = 72 = 11-27(11) cos(m)
72 = 32 + 112-28) (11)cos(p)
82 = 72 + 112 -217 (11) cos(p)

D. 82 = 72 + 112 – 2(7)(11)cos(P)

Step-by-step explanation:

If a = 8, then that means A must be P because the angle corresponds with the side. Therefore, D makes sense because 8^2 is the first part of the equation while cos(P) is at the end.

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4
