Answer:
6
Step-by-step explanation:
The hypotenuse will always be equal to "c." You can put "a" or "b" as 8. This gives us a^2 + 8^2 = 10^2 which simplifies to a^2 + 64 = 100. From there, you simplify (subtract 64, giving you a^2 = 36, and then take the square root of a^2 & 36 to get a = 6 (because 6*6 = 36))
Answer:
6/12
Step-by-step explanation:
Answer: 9 subtracted from y and multiplied by 2
1) vertical (they share a vertex, or midpoint)
2) adjacent (they are next to each other)
Not going to do (1), (2), (3) since they are implicit from (a) and (b) and require graphs (which aren't supported on brainly).
We have 
, that means, if plug in 
we get 
.
Doman of cosine is ![x\in[0,1]](https://tex.z-dn.net/?f=x%5Cin%5B0%2C1%5D)

Hope this helps.
