The nonagon with the sum of 5 angles of 800 and three of the remaining angles equal to the other angle has the equal angle as 120 degrees
<h3 /><h3>What is a nonagon?</h3>
A nonagon is a polygon with 9 sides and interior angles.
Therefore,
sum of interior angles of a nonagon = 1260
let
x = size of the equal angles
800 + 3x + 100 = 1260
900 + 3x = 1260
3x = 1260 - 900
3x = 360
divide both sides by 3
3x / 3 = 360 / 3
Therefore,
x = 120

Answer:
The slope is -2
Step-by-step explanation:
To find the slope we do y2 - y1 / x2 - x1 or in this case, -6 - 2 / 9 - 5
Next, u solve -6 - 2 = -8 and 9 - 5 = 4
So we get -8/4 or simplified -2/1 or -2
The slope is -2
Hope that helps u! :)
Answer:
11.2
Step-by-step explanation:
x is the length of a radius of the circle, all radii have the same length.
the chord of length 20 is perpendicular to the segment of length 5, so the segment bisects the chord , so half of the chord is length 10.
The segment of length 10 is one leg of a right triangle while the segment of length 5 is the other leg. The hypotenuse is also a radius of the circle.
The length of the hypotenuse can be found by they Pythagorean Theorem, a^2 + b^2 = c^2, so
5^2 + 10^2 = c^2 or
25 + 100 = c^2 or
c^2 = 125 or
c = = ≈ 11.2
so if one radius is approximately 11.2, then all radii (including the one of length x) are 11.2
Answer:
y = -1
Step-by-step explanation:
A horizontal line has slope zero (0). Therefore its slope y-intercept form should look like:
Therefore, using the given point (-2, -1) be on this line implies that it satisfies its equation:
Therefore, the equation of the line is:
