What is the sum of all interior angles of a polygon of ^@10^@ sides^@?^@
Answer:
^@ 16 \text{ right angles } ^@
- We know that the sum of all interior angles of a polygon of ^@n^@ sides is ^@ (2n - 4) ^@ right angles.
- @^ \begin{align} \text{ Sum of all interior angles of the polygon of } 10 \text{ sides } &= ( 2 \times 10 - 4 ) \text{ right angles } \\ &= 16 \text{ right angles } \end{align} @^
