What is the difference between regular convex and concave polygons

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]
