Answer:

x = 12

z = 83

Step-by-step explanation:

Supplementary angles, sum = 180

So

8x - 13 + 13x - 59 = 180

21x - 72 = 180

21x = 252

x = 12

z = 8x - 13 (vertical angles are equal)

z = 8(12) - 13

z = 83

Given:

The equation is:

$\dfrac{y}{p-q}=\dfrac{y}{p+q}$

To find:

The value of y.

Solution:

We have,

$\dfrac{y}{p-q}=\dfrac{y}{p+q}$

On cross multiplication, we get

$y(p+q)=y(p-q)$

$yp+yq=yp-yq$

$yp+yq-yp+yq=0$

$2yq=0$

Dividing both sides by 2q, we get

$\dfrac{2yq}{2q}=\dfrac{0}{2q}$

$y=0$

Therefore, the correct option is A.
