If y=8-x then you can plug that into the equation like 7=2-(8-x). When you distribute the equation becomes 7=2-8+x. Once you combine like terms the equation becomes 7=-6+x. Then you subtract 6 from both sides, which gives you 13=x.
To find y just put 13 where x was in the first equation. Y=8-13.
Y=-5
X=13
I think it's touch because they usually rely on the vibrations of the movement in the water in which they know what is in the water. So they feel other fish move around and feel the vibrations of them moving around so they can feel or touch the vibrations.

Answer:
a.11.8
Step-by-step explanation:
You can plug in any of the numbers with second cos to figure this out. cos^-1 (10/11.8) is equal to 32. Which is the angle. So A has to be the answer.
Also cant be c or d because the hypotenuse is larger then any of the other sides.
With B it is about 35
