Answer:
2.57 might be right. If its not then I'm sorry
Answer:
The area of the nonagon is 270cm²
Step-by-step explanation:
The area of a regular polygon is given by

where 'a' is the apothem and 'p' is the perimeter.
The apothem is a=6cm.
The perimeter is p=9×10=90cm.
We substitute the apothem and the perimeter to get:


2 number are x and y
X=10,y=65
<span>2x - 3y - 3z = 8
We've been given the normal vector to the plane <2, -3, -3> and a point within the plane (1, -5, 3). In general if you've been given both the normal vector <a,b,c> and a point (e,f,g) within the plane, the expression for the plane will be:
ax + by + cz = d
and you can compute d by:
d = ae + bf + cg
So let's calculate d:
d = ae + bf + cg
d = 2*1 + -3*-5 + -3*3
d = 2 + 15 + -9
d = 8
And the equation for the plane is
2x - 3y - 3z = 8</span>
X< - 1/8 let me know if Uu need work
