Question

ión, hallar los valores de x y z. 73° z° (9x + 80)°

Explanation:

Step1: Use vertical - angle property

Vertical angles are equal. So, $9x + 80=73$.

Step2: Solve for x

Subtract 80 from both sides: $9x=73 - 80=-7$. Then divide by 9: $x=-\frac{7}{9}$.

Step3: Find z

Since $z$ and the $73^{\circ}$ angle are vertical angles, $z = 73$.

Answer:

$x=-\frac{7}{9}$
$z = 73$
