Statements
Reasons
Given
1. ACICD
AABC is similar to ACED
2.
Property of similar triangles
3. slope of AC =
- AB
Definition of slope
CD
slope of
4. slope of ĀČ x slope of CD AB x D Multiplying the slopes
5. slope of AČ x slope of CD =
E x Ee Substitution property of equality
6. slope of AC x slope of CD = -1
Simplifying the right side
The table shows the proof of the relationship between the slopes of two perpendicular lines. What is the missing statement in step 22

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

college

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
