Answer:
Yes; they are congruent 
SSS
Step-by-step explanation:
Here, we want to check if the given triangles are congruent 
From what we have, we can see that all three sides are marked for both triangles 
So the sides of the triangles are income 
So therefore, the triangles are congruent by SSS

Answer:
7 & 13
Step-by-step explanation:
Let the first number be x
2nd number = 8 less than 3 times the other
2nd number = 3x - 8
Their sum = 20
X + 3x - 8 = 20
4x -8 = 20
Collect like terms 
4x = 20+8
4x = 28
Divide both sides by 4
4x/4 = 28/4
X = 7
First number = 7
2nd number = 3x - 8
= 3(7) - 8
= 21 -8
= 13.
Therefore the numbers are 7 and 13
