Cloverdale River Park a great spot for wildlife viewing, and information about the park's riparian habitat is located along the trail. There are group picnic areas with barbecues and a large parking lot. Both include several wheelchair-accessible spaces. No lifeguard service is available.
Sum of interior angles of an n sided polygon = (2n - 4) * 90 degrees. Let us find the sum of the interior angles of a heptagon. Heptagon is a polygon with 7 sides. Sum of interior angles of a heptagon = (2 * 7 - 4) * 90 degrees. = 900 degrees. If heptagon is regular, then the value of an interior angle is $\frac{900}{7}$ degrees = 128.57 degrees.
Best Answer: Hey there! The sum of all interior angles in a triangle is 180 degrees. The sum of all exterior angles in a triangle is 360 degrees. Use the formula. 180(n-2), where n is the number of sides. 180(3-2), substitute 3 for n. 180(1) subtract 2 from 3. 180 multiply 180 and 1.
