Answer:
y=135
Step-by-step explanation:
To find the solution, we must put 7 in for x and solve, as shown:
![y=310-(25)(7)\\y=310-175\\y=135](https://tex.z-dn.net/?f=y%3D310-%2825%29%287%29%5C%5Cy%3D310-175%5C%5Cy%3D135)
Answer:
![2x-6+x+x=180](https://tex.z-dn.net/?f=2x-6%2Bx%2Bx%3D180)
![4x-6=180](https://tex.z-dn.net/?f=4x-6%3D180)
![4x=180+6](https://tex.z-dn.net/?f=4x%3D180%2B6)
![4x=186](https://tex.z-dn.net/?f=4x%3D186)
![x=\frac{186}{4}=46,5°](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B186%7D%7B4%7D%3D46%2C5%C2%B0)
Step-by-step explanation: the other angle is equal to his simmetrical, cause the triangle is isosceles, so is value is x. The sum of the angle in a triangle must be 180°
