Answer:

Step-by-step explanation:
In any triangle, the cosine/cos of an angle is equal to its adjacent side divided by the hypotenuse (longest side) of the triangle. (a/h)
The angle marked 40 degrees has an adjacent side of
and the hypotenuse of the triangle is 60.
Therefore, we have the equation:

Answer:
A. 
B. $2,307.69
Step-by-step explanation:
You are given the formula

where V = investment earning simple interest
p = principal,
r = interest rate
t = time
So,
A. 
B. r = 0.06 (or 6% as percent)
V = $3,000
t =5
so,

X=5. y=35.
To solve, substitute the 7x into the equation for y. Solve. You get x=5. Then put that into your first equation. Solve. You get y=35. Hope that helps!!
