Point B is collinear with A and C and partitions AC in a 3:4 ratio. B is located at (4,1) and C is located at (12,5). Find the c
GrogVix [38]

Answer:

A(-\frac{20}{3} ,-\frac{13}{3})

Step-by-step explanation:

Point B partitions AC in a 3:4 ratio.

B is located at (4,1) and C is located at (12,5).

Let (x_1,y_1) be the coordinates of A.

Then (\frac{mx_1+nx_2}{m+n}, \frac{my_1+ny_2}{m+n})=(4,1)

But m:n=3:4 implies m=3 and n=4 and (x_2=12,y_2=5)

(\frac{3x_1+4*12}{3+4}, \frac{3y_1+4*5}{3+4})=(4,1)

(\frac{3x_1+48}{7}, \frac{3y_1+20}{7})=(4,1)

\frac{3x_1+48}{7}=4, \frac{3y_1+20}{7}=1

3x_1+48=28, 3y_1+20=7

3x_1=-20, 3y_1=-13

x_1=-\frac{20}{3} , y_1=-\frac{13}{3}

What type of angle is
mash [69]

Answer:

I'm really sorry I can't tell you the answer because you have to measure the angle by yourself using a protractor. But I gave you information about types of angles if you got the degree of angles ( e.g 90 degrees). Hope it helped.

Step-by-step explanation:

acute angle-an angle between 0 and 90 degrees  

right angle-an 90 degree angle  

obtuse angle-an angle between 90 and 180 degrees  

straight angle-a 180 degree angle
