AB = 24
BC = 45
AC = 51
cos C = adjacent / hypotenuse
cos C = BC / AC
cos C = 45/51
Answer:
4
Step-by-step explanation:
Let's say the number of rows in Vanessa's garden is x
Then x/2 + 6 = 8
so x/2 = 8 - 6 = 2
so x = 4
Ambiguous expression. I think you meant:
3x + 7
<span>3x/(x+5)+7/(x+5) = --------------
x+5
There's no "answer." All you can do here is to combine the terms and simpify the resulting sum.
