SOLUTION:
Let the unknown number = x
2 ( x + 1 ) = 4x - 6
2x + 2 = 4x - 6
2x - 4x = - 6 - 2
- 2x = - 8
x = - 8 / - 2
x = 8 / 2
x = 4
FINAL ANSWER:
Therefore, the unknown number is 4.
Hope this helps! :)

Answer:
x= 60.1 degrees
Step-by-step explanation:
The triangle forms a right angle triangle
Opposite side of angle x = 13 ft
Hypotenuse of the triangle = 15
We know the opposite side and the hypotenuse
So we use trigonometric formula sin(x)
![sin(x) = \frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=sin%28x%29%20%3D%20%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
![sin(x) = \frac{13}{15}](https://tex.z-dn.net/?f=sin%28x%29%20%3D%20%5Cfrac%7B13%7D%7B15%7D)
When we move 'sin' to the other side it becomes 'sin^-1'
![x=sin^{-1}(\frac{13}{15})](https://tex.z-dn.net/?f=x%3Dsin%5E%7B-1%7D%28%5Cfrac%7B13%7D%7B15%7D%29)
x = 60.073565
Answer: 1/4
