It has 8 sides.

. Area of Irregular Quadrilateral is calculated by knowing 4 sides and a angle or diagonal of it. SOLUTION The fi gure is a convex octagon. The sum of the interior angles of an octagon equals 1080.

This means that the shape does not have to have equal measurements therefore there are not shortcuts for the perimeter formula Aug 26 2011 Our acreage calculator will quickly tell you how many acres are in an area of land measured in. Lesson 2 homework practice measures of variability email protected. A guard observes an enemy boat from an observation tower at a height of 180 metre above sea level to be at an angle of depression of 600.

Please Let me know If anyone has the solution. Since each of the eight interior angles in a regular octagon are equal in measure each interior angle measures 10808135 as shown below. Interior Angle of a polygon 180 Exterior angle of a polygon.

Finding the Sum of Angle Measures in a Polygon Find the sum of the measures of the interior angles of the fi gure. N 2 180 8 2 180 Substitute 8 for n. Use the Polygon Interior Angles Theorem.

Our maths printables cover all the core topics including solving three-step problems using addition subtraction multiplication and division fractions and percentages working with decimals converting units. Each exterior angle for a regular octagon has an equal measure. If we know the sum of all the interior angles of a regular polygon we can obtain the interior angle by dividing the sum by the number of sides.

The value of the greater angle in radian is A 5p8 B p2 C 3p8 D p8. Year 6 Maths Printable Worksheets. Hence we can say if a polygon is convex then the sum of the degree measures of the exterior angles one at each vertex is 360.

The distance of the boat from the foot of the observation. The angle next to an interior angle formed by extending the side of the polygon is the exterior angle. Use our variety of year 6 maths worksheets to help your child develop the skills they need to solve more complex maths problems.
