Answer:
C° = 71.6056
Step-by-step explanation:
Law of Cosines: c² = a² + b² - 2abcosC°
Step 1: Plug in known variables
29² = 30² + 15² - 2(30)(15)cosC°
Step 2: Evaluate
841 = 900 + 225 - 900cosC°
-59 = 225 - 900cosC°
-284 = -900cosC°
71/225 = cosC°
cos⁻¹(71/225) = C°
C° = 71.6056
And we have our answer!
I too also need this answer.
Answer:
Part A: $336.4
Part B:279.2645625
Step-by-step explanation:

Answer:
you know that 32 is higher than x is you should take away
Step-by-step explanation:
Answer:
x=720/41
Step-by-step explanation:
x-143=1-7.2x
left part +7.2x = right part + 7.2x
8.2x-143=1
left part + 143 = right part +143
8.2x=144
x=720/41
