Step-by-step explanation:
has the lowest ratio
Use the Pythagorean theorem:
![a^2+8^2=10^2\\\\a^2+64=100\ \ \ \ |-64\\\\a^2=36\to a=\sqrt{36}\to a=6\ cm](https://tex.z-dn.net/?f=a%5E2%2B8%5E2%3D10%5E2%5C%5C%5C%5Ca%5E2%2B64%3D100%5C%20%5C%20%5C%20%5C%20%7C-64%5C%5C%5C%5Ca%5E2%3D36%5Cto%20a%3D%5Csqrt%7B36%7D%5Cto%20a%3D6%5C%20cm)
Y =18. You have to add 4y on both sides then you get 1y=18 and just divided
Answer:
x>3
Step-by-step explanation:
let me know if you need explanation !
