Hello,
The nonagon, polygon with 9 sides, can be divided in 9 triangles which area is
a*c/2
a is the apothem et c the side
Center's angle is 360°/9=40°
as a/14=cos 20°, and (c/2)/14=sin 20°
a*c/2=14*14*sin 20°*cos 20°=14*7*sin40°=98*sin 40°=62,993185...
Area of the nonagon is 9*98*sin 40°=882*sin 40°=566,93867... (in²)
Answer:
7 pizzas
Step-by-step explanation:
Using the formula for slope (rise/run) we can calculate how much one pizza cost.
dollars per pizza.
Take the $11 per pizza and divide it by $80 to get 7.2727 pizzas. Since you can not have .2727 of a pizza you round down to 7 pizzas.
Answer:
A theodolite
Step-by-step explanation:
theodolite is a precision instrument that is used to measure the angle in the horizontal and vertical planes and it is the most commonly used in surveying.
A modern developed theodolite consists of a movable telescope that is mounted within two perpendicular axes called the horizontal axis and the vertical axis. Pointing the telescope on a target object will enable measurement of angle with great precision.
