Law of cosines? ? ill give brainlest

hi there!

the correct answer to this question will be: 18.0

Step-by-step explanation:

since the equation for law of cosine is: c^2 = a^2 + b^2 -2ab*cosC

c in this case will be x

a = 16  b = 30

plug these variables into the equation

x^2 = 16^2 + 30^2 - (2*16*30) * cos(30)

you then solve for x and you get 18.0

so what is the question
