Answer:
180°- 3α
Step-by-step explanation:
By angle sum postulate of a triangle.
![m \angle \: A+ m \angle \: B + m \angle \: C = 180 \degree \\ \alpha + 2 \alpha + m \angle \: C = 180 \degree \\ 3 \alpha + m \angle \: C = 180 \degree \\ \huge \red{ \boxed{\angle \: C = 180 \degree - 3 \alpha}} \\](https://tex.z-dn.net/?f=%20m%20%5Cangle%20%5C%3A%20A%2B%20%20m%20%20%5Cangle%20%5C%3A%20B%20%2B%20m%20%5Cangle%20%5C%3A%20C%20%3D%20180%20%5Cdegree%20%5C%5C%20%20%5Calpha%20%20%2B%202%20%5Calpha%20%20%2B%20m%20%5Cangle%20%5C%3A%20C%20%3D%20180%20%5Cdegree%20%5C%5C%20%203%20%5Calpha%20%20%2B%20m%20%5Cangle%20%5C%3A%20C%20%3D%20180%20%5Cdegree%20%5C%5C%20%20%5Chuge%20%5Cred%7B%20%5Cboxed%7B%5Cangle%20%5C%3A%20C%20%3D%20180%20%5Cdegree%20-%203%20%5Calpha%7D%7D%20%20%20%5C%5C%20)
I think the answer would be A,B and E
Step-by-step explanation:
substitution:
7x-9= 3x-1
4x= 8
x=2
Answer:
I believe the first question is the third option. I hope this helps!
Answer:
