Learning. Task 2 Consider each convex polygon with all possible diagonals drawn from one vertex. By doing this, you can actually form triangles within each polygon. Complete the table below by writing down the number of sides and the number of triangles formed from the given polygons. Since we know that the sum of interior angles of one triangle is equal to 180°, we can now compute for the sum of interior angles of each of the given polygons by simply multiplying the number of triangles formed by 180° Refer to the given figure and find the value of x 3. The stop sign shown is in the shape of a regular octagon. Find the measure of one of its exterior angles ​
