59°

Step-by-step explanation:

According to the given description, $\angle QRS$ is the exterior angle of $\triangle PQR$

So, by exterior angle property of a triangle, we have:

$m\angle QRS=m\angle RPQ+m\angle PQR\\\\(10x - 1)\degree = (3x +17)\degree+(2x +12)\degree\\\\(10x - 1)\degree = (3x +17+2x +12)\degree\\\\(10x - 1)\degree = (5x +29)\degree\\\\(10x - 1)= (5x +29)\\\\10x - 5x = 29 + 1\\\\5x = 30\\\\x = \frac{30}{5}\\\\x = 6\\\\\because m\angle QRS = (10x - 1)\degree \\\\\therefore m\angle QRS = (10\times 6- 1)\degree \\\\\therefore m\angle QRS = (60- 1)\degree \\\\\huge\orange{\boxed{\therefore m\angle QRS = 59\degree }}\\$

$\bold{z=\dfrac{pd+59}{p+2}}$

Step-by-step explanation:

-p(d + z) = -2z + 59

-pd - pz = -2z + 59

+pd +pd

-pz = pd - 2z + 59

+2z +2z

pz + 2z = pd + 59

(p + 2)z = pd + 59

÷(p+2) ÷(p+2)

$\bold{z=\dfrac{pd+59}{p+2}}$
