Answer:
∠A = 94º
∠C = 86º
Step-by-step explanation:
You just need to know that the sum of the two angles in a parallelogram must be equal to 180º. Let's make an equation.
![(5y-3)+(3y+27)=180](https://tex.z-dn.net/?f=%285y-3%29%2B%283y%2B27%29%3D180)
Solve;
![5y-3+3y+27=180](https://tex.z-dn.net/?f=5y-3%2B3y%2B27%3D180)
Combine like terms;
![8y+24=180](https://tex.z-dn.net/?f=8y%2B24%3D180)
Subtract 24
![8y=180-24](https://tex.z-dn.net/?f=8y%3D180-24)
![8y=156](https://tex.z-dn.net/?f=8y%3D156)
Divide by 8
![y=\frac{156}{8}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B156%7D%7B8%7D)
Simplify.
![y=\frac{39}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B39%7D%7B2%7D)
Replace;
∠A = ![5y-3](https://tex.z-dn.net/?f=5y-3)
![5(\frac{39}{2})-3\\ \frac{195}{2}-3\\ \frac{195-2*3}{2}\\](https://tex.z-dn.net/?f=5%28%5Cfrac%7B39%7D%7B2%7D%29-3%5C%5C%20%5Cfrac%7B195%7D%7B2%7D-3%5C%5C%20%5Cfrac%7B195-2%2A3%7D%7B2%7D%5C%5C)
![\frac{195-6}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B195-6%7D%7B2%7D)
≅ 94
----------------------------------------------------------------------------------------------
∠C =
![3y+27\\3(\frac{39}{2})+27](https://tex.z-dn.net/?f=3y%2B27%5C%5C3%28%5Cfrac%7B39%7D%7B2%7D%29%2B27)
![\frac{117}{2}+27](https://tex.z-dn.net/?f=%5Cfrac%7B117%7D%7B2%7D%2B27)
![\frac{117+27*2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B117%2B27%2A2%7D%7B2%7D)
![\frac{117+54}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B117%2B54%7D%7B2%7D)
≅86
Patterns of the ones digit is just counting by ones and in the exercise 13 14 as you can see is also counting by ones
