Answer:
y=5x+10 or y=25 (i'm not sure what they're asking)
The value of x is 5. Angle one and four are vertical. You can do this by writing 7x = 3x + 20. Isolate the variable by moving 3x to the other side. If you do this, 3x becomes negative, and you end up with 7x-3x = 20 --> 4x = 20.

AB= (125*10)/10=125
is AB =125 then AC is duble AC= 2*125=250
