Which equation could be used to solve for the length of side c, given a = 5, b = 12, and C = 72°?

Answers

Answer 1

Answer:

i had this question before

Step-by-step explanation:

c^2=a^2+b^2-2abcos(c)

c=sqrt(a^2+b^2-2abcos(c))

c=sqrt((5)^2+(12)^2-2(5)(12)cos(72))

c=sqrt(25+144-120cos(72))

c=sqrt(169-120cos(72))

c=sqrt(169-37.08)

c=sqrt(131.92)

c=11.49

Lynn took a taxicab from the office to the airport. She paid $4 per mile plus a $6 flat fee. Her total cost was $66. How many miles was the trip?

Answers

Answer:

12

Step-by-step explanation:

Answer:

15 miles

Step-by-step explanation:

To answer this question, we must break up the question. First, we know Lynn paid a total of $66 for the trip. She had to pay $4 per mile, and the flat fee was $6, meaning that no matter how many miles they rode, she had to pay an extra $6 on top of that. So, we can subtract the total cost by the flat fee:

66 - 6 = 60

Then, we divide that number by the amount it costs to ride each mile, which is 4:

60 / 4 = 15

So, Lynn's trip was 15 miles

Hope this helps :)

System of Equations:

8s + 7c = 211

4s + 6c = 138

I used the elimination method and multiplied the second equation by -2

-8s - 12c = -276

add the above to the first equation and get

-5c = -65

c = 13

now find s

8s + 7(13) = 211

8s + 91 = 211

8s = 120

C. 7(h-6k)(h+6k)
D. None of these

252 = 7 *36

36 = 6 *6 = 6²

a² -b²  = (a + b)(a - b)

7h² - 252k² =  7(h² - 36k²)
