Answer:
Point N will be located between 0 and -1.
Step-by-step explanation:
Points A and D are placed at (-4, 0) and (4, 0) on a number line.
We have to find the location of a point N which divides AD in the ratio of 3 : 4.
Coordinates of a point (x, y) which divides a segment with extreme ends at
and
in the ratio of m : n is given by,
x = ![\frac{mx_2+nx_1}{m+n}](https://tex.z-dn.net/?f=%5Cfrac%7Bmx_2%2Bnx_1%7D%7Bm%2Bn%7D)
y = ![\frac{my_2+ny_1}{m+n}](https://tex.z-dn.net/?f=%5Cfrac%7Bmy_2%2Bny_1%7D%7Bm%2Bn%7D)
By this formula, coordinates of the point N will be,
x = ![\frac{3(4)+4(-4)}{3+4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%284%29%2B4%28-4%29%7D%7B3%2B4%7D)
x = ![-\frac{4}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B7%7D)
y = 0
Therefore, coordinates of the point N are
.
Point N will be located between 0 and -1.
The angle x and 70 are alternate interior so that means they measure the same.
In an isoceles triangle the base angles are the same so that means that both the x angles are 70.
Now we can subtract their sum by 180 to find the measure of angle 1.
180 - (70 + 70) = 40
So the measure of angle 1 is 40.
Hope this helps :)<span />
