Answer:
Right angles are congruent
Step-by-step explanation:
One right angle can be transformed to another using rigid transformations such as translation ,rotation and reflection.This is basically the definition of congruence because the idea is to transform one object to another.
Here is a substitution problem. By saying c is 4, we can replace anywhere we see c with the number 4.
c = 4
4c - 7.8
= 4(4) - 7.8
= 16 - 7.8
= 8.2
Hope this helps! :)

X=1
A)He can cut 5 strips of of 7/10m.
7/10=0.7m
0.7*5=3.5m

b)Leftover will be 0.6m.
4.1-3.5=0.6m
Answer:

Step-by-step explanation:
So the thing about adding of integers is that is both nos. are positive then you can simply add it and same with negative too.But with negative and positive we should subtract but that is for later.Luckily we have 2 positive integers so we do it like this:
+6 is the same as 6 and +2 is the same as 2 so we...
rule:add the numbers and add the sign.
