What is the value of x?

Answer:
[tex]X= 15[/tex]
Step-by-step explanation:
Since the angles are equal the equation to solve would be:
[tex]3x + 20 = 5x - 50[/tex]
you will subtract 3x from 5x and get 2x
[tex]20 = 2x -50[/tex]
subtract 20 from 50 to get 30
[tex]2x= 30[/tex]
divide each side by 2
[tex]\frac{2x}{2} = \frac{30}{2}[/tex]
[tex]X= 15[/tex]
Hope this helps
