Answer:

Cosine

Step-by-step explanation:

Cosine = \frac{adjacent}{hypothenuse}

Cos 70 = \frac{x}{8}

0.633 = \frac{x}{8}

0.633 x 8 = \frac{x}{8} x 8

5.064 = x

Need help with this problem?
yuradex [85]

The total amount raised is the sum of the amounts raised by the car wash and the dinner. The car wash raised 7c - 18. The dinner raised 6s - 45. We now add the expressions and combine like terms.

7c - 18 + 6s - 45

We need to combine like terms. Like terms are terms that have the same variables and the same exponents on the variables. 7c and 6s are not like terms since c and s are different variables. They cannot be combined together. Plain numbers, like -18 and -45 are lime terms because their variable parts are the same; they both have no variables.

7c - 18 + 6s - 45 =

= 7c + 6s - 18 - 45

= 7c + 6s - 63

Answer:  C.  7c + 6s - 63

F sin Θ = 5/6 , what are the values of cos Θ and tan Θ?
strojnjashka [21]
We can use inverse sin to calculate the angle, and we get around 56 degrees (but for the answer I'll give the most accurate one). For cos we get around 55, and for tan we get .25. 

I might have done tan wrong but I hope you get the point.
