Answer:

Step-by-step explanation:

  • (5x+39)° and 71° are in a straight line therefore their summation will have to give us 180°(supplementary angles)
  • 5x+39°+71°=180°
  • 5x=180°-39°-71°
  • 5x=70

°[tex]\frac{5x}{5} =\frac{70}{5} \\x=14\\[/tex]     z is vertically opposite to 71° therefore z= 71°
