Saul creates a piece of art. He begins with the figure shown, where stack Z Y with left right arrow on top space parallel to space stack A B with left right arrow on top and m angle W Z X equal 82 degree. MAGEO091210309_1.gif

Saul draws a line located below and parallel to stack A B with left right arrow on top that intersects stack Z A with left right arrow on top at C and stack Z B with left right arrow on top at D. The measure of angle B D C equal 56 degree. What is the measure of angle A C D ?

angle ACD=  138 degrees

Step-by-step explanation:

As angle W Z X is  opposite to the angle CZD. Angle CZD is also 82 degree.

If we consider the triangle CZD the angle D  is equal to 180 - 56 =  124 degrees.( angles on a straight line= 180)

The sum of the angles of a triangle is equal to 180 degrees

<C+<D +<Z= 180

<C= 180- 82-56

<C= 42 degrees

Since Angle DCZ= 42 degrees

angle ACD= 180-42  ( angles on a straight line)

angle ACD=  138 degrees

Check

angle ACD+Angle BDC+Angle ABD + angleCAB

138+ 56+124+42 = 360 degrees

answer: e 9, 5.75

step-by-step explanation:

step 1

find the variation ab in the x coordinate

delta x=(x2-x1)=10-> 8 units

find the variation ab  in the y coordinate 

delta y=(y2-y1)=6-> 2 units

step 2

find the coordinates point c

  x coordinate 

cx=ax+delta x*2/> cx=2+8*(2/> cx=3

  y coordinate 

cy=ay+delta y*2/> cy=4+2*(2/> cy=4.25

the coordinates of point c are (3,4.25)

step 3

find the coordinates point d

  x  coordinate 

dx=ax+delta x*4/> dx=2+8*(4/> dx=4

  y  coordinate 

dy=ay+delta y*4/> dy=4+2*(4/> dy=4.5

the coordinates of point d are (4, 4.5)

step 4

find the coordinates point e

  x  coordinate 

ex=ax+delta x*4/> ex=2+8*(6/> ex=5

  y  coordinate 

ey=ay+delta y*4/> ey=4+2*(6/> ey=4.75

the coordinates of point e are (5, 4.75)

step 5

find the coordinates point f

  x  coordinate 

fx=ax+delta x*4/> fx=2+8*(8/> fx=6

  y  coordinate 

fy=ay+delta y*4/> fy=4+2*(8/> fy=5

the coordinates of point f are (6,5)

step 6

find the coordinates point g

  x  coordinate 

gx=ax+delta x*4/> gx=2+8*(10/> gx=7

  y  coordinate 

gy=ay+delta y*4/> gy=4+2*(10/> gy=5.25

the coordinates of point g are (7,5.25)

step 7

find the coordinates point h

  x  coordinate 

hx=ax+delta x*4/> hx=2+8*(12/> hx=8

  y  coordinate 

hy=ay+delta y*4/> hy=4+2*(12/> hy=5.5

the coordinates of point h are (8,5.5)

step 8

find the coordinates point i

  x  coordinate 

ix=ax+delta x*4/> ix=2+8*(14/> ix=9

  y  coordinate 

iy=ay+delta y*4/> iy=4+2*(14/> iy=5.75

the coordinates of point i are (9,5.75)
