Answer:

20cos(39) or 15.543 (3 d.p.)

Step-by-step explanation:

Use SOHCAHTOA
You want to find A and have an angle of 36° and H
So use CAH
cos(39) = x / 20
x = 20cos(39)

Point C is located at (1, 2) and point D is located at (−4, −2). Find the x value for the point that is 1 over 4 the distance fr

stellarik [79]

Answer:

-0.25

Step-by-step explanation:

Coordinates of C = $(x_{1} ,y_{1} )=(1,2)$

Coordinates of D = $(x_{2} ,y_{2} )=(-4,-2)$

Let Coordinates of A= (x,y)

Since A point is located 1/4 the distance from C to D

So the remaining distance from point A to D is 3/4

Thus the ratio of CA : AD = m:n=1:3

Now to find points of A we will use section formula i.e.

$x=\frac{mx_{2}+nx_{1}}{m+n}$

$y=\frac{my_{2}+ny_{1}}{m+n}$

Substituting the values:

$x=\frac{1*-4+3*1}{1+3}$

$x=\frac{-1}{4}$

$x=-0.25$

Thus Find the x value for the point that is 1 over 4 the distance from point C to point D is -0.25

Hence option a is correct
