Answer:
what can i help u with
Step-by-step explanation:
I really can't help u with that sorry i am bad at math
-9, -3 is the answer to your problem.
How do u solve perimeter and circumfrence
we know that
triangles BCD and ACE are similar
so, their ratios of sides must be equal
Calculation of y:
![\frac{BC}{AC}=\frac{CD}{CE}](https://tex.z-dn.net/?f=%5Cfrac%7BBC%7D%7BAC%7D%3D%5Cfrac%7BCD%7D%7BCE%7D)
we can see that
AC=AB+BC
AC=y+3
CE=CD+DE
CE=4+6
CE=10
now, we can plug values
![\frac{3}{y+3}=\frac{4}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7By%2B3%7D%3D%5Cfrac%7B4%7D%7B10%7D)
now, we can solve for y
![3*10=4*(y+3)](https://tex.z-dn.net/?f=3%2A10%3D4%2A%28y%2B3%29)
![30=4y+12](https://tex.z-dn.net/?f=30%3D4y%2B12)
![30-12=4y+12-12](https://tex.z-dn.net/?f=30-12%3D4y%2B12-12)
![18=4y](https://tex.z-dn.net/?f=18%3D4y)
![y=4.5](https://tex.z-dn.net/?f=y%3D4.5)
Calculation of AC:
we know that
AC=y+3
we can plug y
and we get
![AC=4.5+3](https://tex.z-dn.net/?f=AC%3D4.5%2B3)
