‼️SOS<br><br> lIn the diagram above, PQR and QST are straight lines. Find the value of x + y.

OleMash [197]

$\\ \sf\longmapsto x+144=180$ (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

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

Answer:

$48 {m}^{5} {n}^{6}$

Step-by-step explanation:

$6{m}^{3} {n}^{3} \times 8 {m}^{2} {n}^{3}$

$8 \times 6 = 48$

So

$6{m}^{3} {n}^{3} \times 8 {m}^{2} {n}^{3} = 48 {m}^{3 + 2} {n}^{3 + 3}$

Therefore

$48 {m}^{5} {n}^{6}$
