Look at the figure below: Triangle ABC is a right triangle with angle ABC equal to 90 degrees. The length of AC is 5 units, and the length of AB is 4 units. D is a point above C. Triangle ADC is a right triangle with angle DAC equal to 90 degrees and DC parallel to AB.

What is the length, in units, of segment CD?

8
9
6.25
7.25

the answer is two. hope this !

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

none.

step-by-step explanation:

m1=5

b

b=-1

find the slope and y-intercept of the second equation.

m2=0

b

b=-6

compare the slopes

m of the two equations.

,

m

2

=

0

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

m1=5,m2=0

$450 i think. hope this ☺
