What do you mean by that?
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!
Answer:
(16.5 + 1.5n)° = (12 + 2n)° [given]
=> 16.5 – 12 = 2n – 1.5n
=> 4.5 = 0.5n
=> n = 4.5/0.5
=> n = 9
