Answer: </h3><h3>
x = 58</h3><h3>
y = 32</h3>
=============================================
Explanation:
If angle x is the reference angle, then the side 9 is the adjacent side (it is the closer leg to angle x). The hypotenuse is 17 as it is opposite the largest angle. The largest side is always opposite the largest angle in a triangle.
-----------------
cos(angle) = adjacent/hypotenuse
cos(x) = 9/17
x = arccos(9/17)
x = 58.034281249203
x = 58
Arccosine is the same as inverse cosine, written as 
Make sure your calculator is in degree mode.

Edit:
After finding x, we can find y
x+y = 90
58+y = 90
y = 90-58
y = 32
1st day = 1/12
2nd day = 2/12
3rd day = 3/12
4th day = 4/12
5th day = 5/12
6th day would be = 6/12
If it continues in that order, the sum of the walks would total 1 mile when:
They all add up to 12/12
Add = 1/12 + 2/12 + 3/12 + 4/12 = 10/12
That is still not up to 12/12
So we add up the 5th day also = 10/12 + 5/12 = 15/12 = 1 3/12 miles
So on the 5th day the sum of his walks total at least 1 completed mile.
At least 1 means 1 and above. As you can see the answer we got 1 3/12 is already more than 1.
Answer:
3/5
Step-by-step explanation:
9/15
Divide the top and bottom by 3
9/3 =3
15/3 =5
9/15 = 3/5
We have:
f: <span>the amount of money that Frank spent.
r = the amount of money that Rachel spent.
</span>
The system of equations that represents this situation is:
1) f+r=15.75
2)r=2f
Let's substitute r=2f into the equation 1):
f+r=15.75
f+2f=15.75
3f=15.75
f=15.75/3
f=5.25
Now, we must substitute f=5.25 into the second equation, as it shows below:
r=2f
r=2x5.25
r=10.50
<span>
How much money did they each spend?</span> The answer is:
Frank spent 5.25$ and Rachel spent 10.50$
