Answer:
54
Explanation:
We know that 2x + 4 and Angle 1 are corresponding angles, meaning they are same. With this in mind, You know that 2x + 4 and 5x + 1 = 180 because any angle on a straight line cut by a transversal will always add up to 180. You can then use algebra to figure out x = 25, plug x back into 2x + 4, and get 54.
How to solve for X:
2x + 4 + 5x + 1 = 180 (Add like terms)
7x + 5 = 180 (Remove 5 from both sides)
7x = 175 (Divide by 7)
x = 25
