Vertex is -1,2.................
I think they are congruent because two of their lines are the same and the both have a 90 degree angle. I think they are congruent from the SAS postulate.
Answer:
10 and 14
Step-by-step explanation:
You need only check the answers to see which one satisfies the problem requirements. The differences between the second and first numbers are ...
8, 4, 2, -6
Only one pair has the second number 4 more than the first: 10 and 14.
_____
Since you are given variable definitions, perhaps you're expected to write and solve equations.
a + b = 24 . . . . . the sum of the two numbers is 24
-a +b = 4 . . . . . . the second number is 4 more than the first
Adding these two equations gives ...
(a +b) +(-a +b) = (24) +(4)
2b = 28 . . . . . simplify; next, divide by 2
b = 14 . . . . . . . identifies 10 and 14 as the correct answer
