Given the triangle below, what is mc, rounded to the nearest tenth?

41.4

Step-by-step explanation: Since this isn't a right triangle and you're given side side side (SSS), you need the Law of Cosines.

cos(c) = (a^2 + b^2 - c^2)/2ab

(100+144-64)/2*12*10

cos(c) = 180/240

multiply both sides of the equation by cos^-1 to get ride of cos:

cos^-1(cos(c)) = cos^-1(180/240)

c = 41.4

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
