Divide the nonagon radially into 9 congruent, equilateral isosceles triangle. Each triangle has vertex angle of 360°/9 = 40°.
Interior angle of polygon = 180°-40° = 140°.
Sum of interior angles = 9(140°) = 1260°
If you would like to write x = 1/3 * y in general form, you can do this using the following steps:
The general form of the equation is: ax + by + c = 0.
x = 1/3 * y
x - 1/3 * y = 0
The correct result would be x - 1/3 * y = 0.
Answer:
3/8ths of 680 kcal or 3 x 85 = 255 kcal.
Step-by-step explanation:
3/8ths of 680 kcal or 3 x 85 = 255 kcal.
Answer:e
Step-by-step explanation:
The equation for the submarine is given as y =-240x
Where y is the distance of the descent
x is the time in hours
and -240 is the rate of distance per unit time
To calculate how long it will take this submarine to reach the descent
x = y /-240
Answer:
Step-by-step explanation:
Having drawn the line, Kendall must verify that the point P belongs to the line y = 2x-1 and then calculate the distance between A-P and verify if it is the closest to A or there is another one of the line
Having the point P(3,5) substitue x to verify y
y=2*(3)-1=6-1=5 (3,5)
Now if the angle formed by A and P is 90º it means that it is the closest point, otherwise that point must be found
and we found the distance PQ and QA
; 
, 
be the APQ triangle we must find <APQ through the cosine law (graph 2).
