Select True or False for each statement. In the ordered pair (3, 5), the number 5 is the y-coordinate.
The origin has coordinates ( 0, 0 )
The horizontal axis in a coordinate plane is the y-axis.

1. true

2. true

3. false

Step-by-step explanation:

1. 3=x , 5=y

2. origin is always going to have the coordinates of (0,0)

3. horizontal is the y axis and the vertical line is the x axis.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
