For a 7 sides polygon which is called heptagon or septagon
Interior angles = (7-2)*180/7 = 128.57°
Exterior angle = 180 - 128.57 = 51.43°
Central angle = 360/7 = 51.43°
The statements which are correct:
<span>3. The regular polygon ABCDEFG can be broken down into 2 isosceles trapezoids and 1 isosceles triangle
</span>
<span>5. The central angle of the polygon ABCDEFG is about 51.43° and each interior angle is about 128.57°
</span>
<span>7. The central angle ABCDEFG is the same measure of the exterior angle
</span>

Answer:72 are boys.
Step-by-step explanation:
40%of 180 is 72.
Answer:
6.7i + 7.4j
Step-by-step explanation:
if the angle starts from the East (direction of positive x-axis)
then the y (j) component is 10*sin(42) = 6.7
and x (i) component is 10*cos(42) = 7.4
