165 divided by 11 equals 15
Answer:
x = 24
Step-by-step explanation:
ABCD is a parallelogram.
Angle B and Angle C are adjacent (successive) angles.
Adjacent angles of a parallelogram are supplementary.
Therefore,
![(5x) \degree + (2x + 12) \degree = 180 \degree \\ \\ (5x + 2x + 12) \degree = 180 \degree \\ \\ (7x+ 12) \degree = 180 \degree \\ \\7x+ 12 = 180 \\ \\7x = 180 - 12 \\ \\ 7x = 168 \\ \\ x = \frac{168}{7} \\ \\ x = 24](https://tex.z-dn.net/?f=%285x%29%20%5Cdegree%20%2B%20%282x%20%2B%2012%29%20%5Cdegree%20%3D%20180%20%5Cdegree%20%5C%5C%20%20%5C%5C%20%285x%20%2B%202x%20%2B%2012%29%20%5Cdegree%20%3D%20180%20%5Cdegree%20%5C%5C%20%20%5C%5C%20%287x%2B%2012%29%20%5Cdegree%20%3D%20180%20%5Cdegree%20%5C%5C%20%20%5C%5C7x%2B%2012%20%3D%20180%20%5C%5C%20%20%5C%5C7x%20%3D%20180%20-%2012%20%5C%5C%20%20%5C%5C%207x%20%3D%20168%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B168%7D%7B7%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%2024)
The answer is letter c, also just a tip, all i had to do was ask siri :)
Answer:
x = -1
Step-by-step explanation:
Answer:
1. Add 6 to both sides, cause that is the inverse of subtraction, so you get 5x = 50 as 6 cancels 6 out.
2. Divide 5 from both sides and get x = 10
