Given the figure below, find the values of x and z. (5x + 86) (10x + 34) X = 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
