Given the figure below, find the values of x and z.<br> (5x + 86)<br> (10x + 34)<br> X =<br> Z=
kolezko [41]

Answer:

x = 4 \\ z = 106

Step-by-step explanation:

(5x + 86) + (10x + 34) = 180 \\ 15x + 120 = 180 \\ 15x = 180 - 120 \\ 15x = 60 \\  \\ x =  \frac{60}{15}  \\  \\ x = 4

(5x + 86) = 5(4) + 86 = 20 - 86 = 106

Z= 106 —> Opposite angles

I hope I helped you^_^
