X equals 80 degrees and y equals 130 degrees
divide total miles by total time:
60.9 / 3.5 = 17.4 miles per hour
The answer is 30
Explanation:
So all of the angles in a triangle add up to 180 degrees and so if you split the triangle into separate triangles then you can add up the angles that are known and subtract from 180 to get the size of the missing angle e.g 90 + 56 = 146, 180 -146 = 34 for the other triangle 90 + 26 = 116, 180 - 116 = 64 and so 64 - 34 = 30

Step-by-step explanation:
For this exercise you need to remember the multiplication of signs:
![(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-](https://tex.z-dn.net/?f=%28%2B%29%28%2B%29%3D%2B%5C%5C%28-%29%28-%29%3D%2B%5C%5C%28-%29%28%2B%29%3D-%5C%5C%28%2B%29%28-%29%3D-)
1. Given:
![(4x + 2.2)(3x - 5)](https://tex.z-dn.net/?f=%284x%20%2B%202.2%29%283x%20-%205%29)
Apply the Distributive property:
![=12x^2+6.6x-20x-11](https://tex.z-dn.net/?f=%3D12x%5E2%2B6.6x-20x-11)
Add the like terms:
![=12x^2-13.4x-11](https://tex.z-dn.net/?f=%3D12x%5E2-13.4x-11)
You can idenfity that:
- Degree: 2
