Respuesta :

Because the angles are equal you will want to set the expressions equal to each other.
 
3x+50=6x-10

Subtract the 3x on both sides.

50=3x-10

Add the 10 on both sides.

60=3x

To get x by itself divide 3 on both sides.

20=x
The value of x would be 9x because u would add the 3x +6x = 9x
