Answer:
the sum is -4
Step-by-step explanation:
Cosine = adjacent / hypotenuse
So that means the adjacent side = 15 and the hypotenuse = 17
By Pythagorean Theorem, we know that
opposite^2 = hypotenuse^2 - adjacent^2
opposite^2 = 17^2 - 15^2
opposite^2 = 289 - 225
opposite^2 = 64
opposite side = 8
sine = opposite / hypotenuse
So,
sine A = 8 / 17
Well, to find the circumference of a circle, we can use the formula
C=2
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
r.
So just plug in 3.5 into the formula.
C=2
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
3.5.
Multiply and we get C=21.99. which is about 22
So our answer would be C. 22 feet.

Answer: m = $52
Explanation:
Tickets (t) = $8
Popcorn & Soda (s)= $5
Friends = 4
Since all friends bought the same thing the equation will be set as
4(t +s) = m OR 4t +4s = m
Using substitution, you plug each variable
t = 8 and s = 5
4((8) + (5)) = m
4(8+5) = m => 4(13) =m => 52=m
OR
4(8) + 4(5) = m => 32 + 20 = m =>
52 =m
