$\\ \sf\longmapsto x+2x+90=180$

$\\ \sf\longmapsto 3x+90=180$

$\\ \sf\longmapsto 3x=180-90$

$\\ \sf\longmapsto 3x=90$

$\\ \sf\longmapsto x=\dfrac{90}{3}$

$\\ \sf\longmapsto x=30$

Now

$\\ \sf\longmapsto x=2y$ (Opposite interior angles)

$\\ \sf\longmapsto 2y=30$

$\\ \sf\longmapsto y=\dfrac{30}{2}$

$\\ \sf\longmapsto y=15$

And

$\\ \sf\longmapsto x+z=180$

$\\ \sf\longmapsto z+30=180$

$\\ \sf\longmapsto z=180-30$

$\\ \sf\longmapsto z=150$

-5

Initial value is y-intercept where x is 0 (0,y)

so

(0,-1) is starting point
