C) is the answer 1800/36=50
Answer:
![(61x + 3) = 125 \degree](https://tex.z-dn.net/?f=%2861x%20%2B%203%29%20%3D%20125%20%5Cdegree)
![(25x + 5) =55 \degree](https://tex.z-dn.net/?f=%2825x%20%2B%205%29%20%3D55%20%5Cdegree)
Step-by-step explanation:
The first angle us (61x+3)
The second angle is (25x+5)
We use corresponding angles to get the top angle as a linear pair to (25x+5).
We use sum of angles on a straight line to obtain:
![(61x + 3) + (25x + 5) =180 \degree](https://tex.z-dn.net/?f=%2861x%20%2B%203%29%20%2B%20%2825x%20%2B%205%29%20%3D180%20%5Cdegree)
Group similar terms
![61x + 25x = 180 - 3 - 5](https://tex.z-dn.net/?f=61x%20%2B%2025x%20%3D%20180%20-%203%20-%205)
![86x = 172](https://tex.z-dn.net/?f=86x%20%3D%20172)
![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
We substitute to get:
![(61x + 3) = 61 \times 2 + 3 = 125 \degree](https://tex.z-dn.net/?f=%2861x%20%2B%203%29%20%3D%2061%20%5Ctimes%202%20%2B%203%20%3D%20125%20%5Cdegree)
![(25x + 5) =25 \times 2 + 5 = 55 \degree](https://tex.z-dn.net/?f=%2825x%20%2B%205%29%20%3D25%20%5Ctimes%202%20%2B%205%20%3D%2055%20%5Cdegree)

then x is not 7
proof
for x=7, 35+49 <100
