Answer: x=12

Step-by-step explanation:

m\angle1=(x+13)^0 \ \ \ \ \    m\angle2=39^0\ \ \ \ m\angle3=(5x+4)^0\\

The sum of the angles of the triangle is 180°:

(x+13)+39+(180-(5x+4))=180\\\\x+13+39+180-5x-4=180\\\\-4x+48=0\\\\-4x+48+4x=0+4x\\\\48=4x

Divide both parts of the equation by 4:

12=x\\\\Thus,\ x=12
