lIn the diagram above, PQR and QST are straight lines. Find the value of x + y.

Answer 1

`\\ \sf\longmapsto x+144=180`(Supplementary)

`\\ \sf\longmapsto x=180-144`

`\\ \sf\longmapsto x=36`

And

`\\ \sf\longmapsto y+40=180`

`\\ \sf\longmapsto y=180-40`

`\\ \sf\longmapsto y=140`

Now

`\\ \sf\longmapsto x+y=140+36=176`
