We can't tell. We need to know how the angles N and L are related.
Answer:
The midpoint is
( (x1+x2)/2, (y1+y2)/2)
Step-by-step explanation:
To find the x coordinate of the midpoint
(x1+x2)/2
To find the x coordinate of the midpoint
(y1+y2)/2
The midpoint is
( (x1+x2)/2, (y1+y2)/2)
Answer:
40°
Step-by-step explanation:
1. Shape of a nonagon: <em>9</em> (root non-)
2. Total exterior angle: <em>360°</em> (constant for all polygons)
3. Given that this polygon is regular, the one exterior angle of an nonagon is <em>360°/9</em> = 40°.
Answer:
Jessica lived 10 months in Spain and 8 months in Colombia.
Step-by-step explanation:
Let x be the months Jessica spent in Spain, and y the months she spent in Colombia:
1. x + y = 18
Using the information of words per month learned in each country, we can also write the equation:
2. 160 * x + 200 * y = 3200
So now we have a system of <u>two equations and two unknowns</u>.
First we <u>express y in terms of x, in the first equation</u>:
We <u>replace y in the second equation</u>:
- 160 * x + 200 * (18 - x) = 3200
And <u>solve for x</u>:
- 160x + 3600 - 200x = 3200
Finally we <u>use that value of x in the first equation and solve for y</u>:
Jessica lived 10 months in Spain and 8 months in Colombia.
