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!

Step-by-step explanation: IM MAKING A GUESS IF ITS WRONG IM SORRY I TIRED
Step-by-step explanation:
x+3=8
8-5=3 so x=5
7+5=12 / 12-7=5
