Answer:
71.6056
Step-by-step explanation:
c² = a² + b² - 2abcosC°
29² = 30² + 15² - 2(30)(15)cosC°
841 = 900 + 225 - 900cosC°
-59 = 225 - 900cosC°
-284 = -900cosC°
71/225 = cosC°
cos⁻¹(71/225) = C°
C° = 71.6056
Basically this app helps you with any question you need you got to ask a question and people will answer it for you just like i am doing now also you can answer other peoples questions to get points.
You did not include the problem therefore i cannot help you with this but if you could message me the problem i’d be happy too
You add 7+5 together to get 12, then you multiply 12 by 6 and get 72, then you add the 3 to 72 and get 75. 6(7+5)+3. Hope this helps with the problem!!
A=π(10t)2=100πt2
B.
A=100×3.14×32=2826
