Remember your prefixes! They help a lot, because there is a formula for this particular problem. Nonagon refers to a shape with 9 sides.
The number of triangles a polygon has is represented by the formula:
(n-2)
Where "n" is the number of sides. If you ever forget what you subtract "n" by think of a triangle. It has 3 sides, so it is only logical that you should only have 1 triangle (subtract by 2). So, what is the sum of the interior angles of a triangle, 180°. So the formula looks like this:
Sum of Interior Angles = 180°(n-2)
180°(9-2)
180°(7) = 1260° is the sum of interior angles for a nonagon!

x has to be at least 50% => 50% is the lower bound
=> x ≥ 50
Answer: x ≥ 50

The measure of angle CAR is 65 degrees!
<span>Find the value of "x": 5x = 25. Step 1 : The product is 25 and the given divisor is 5 . Given 5x = 25 . Divide by 5 on both the sides. 5 x 5 = 25 5</span>
V=(4/3)pir^3
SA=4pir^2
so
V=288=(4/3)pir^3
times both sides by 3/4
216=pir^3
divide both sides by pi
216/pi=r^3
cube root both sides
6/(∛pi)=r
sub into other
sa=4pir^2
sa=4pi(6/(∛pi))^2
SA=4pi(36/(∛(pi²)))
SA=144pi/(∛(pi²))
SA=144pi∛pi/pi
SA=144∛pi
SA≈210.901 in²
