Answer:
A. 16; 36
Step-by-step explanation:
If the triangles are equal
sides QS = side TV
3v+1 = 5v-9
subtract 3v from each side
3v+1 -3v = 5v-3v-9
1 =2v-9
add 9 to each side
1+9 = 2v-9+9
10 = 2v
divide by 2
10/2 =2v/2
5=v
QS = TV = 3v+1 = 3(5)+1 = 16
<r = <u
4n+4 = 5n-4
subtract 4n from each side
4n+4 -4n = 5n-4n -4
4 = n-4
add 4 to each side
4+4 =n-4+4
8 =n
<r = <u = 4n+4 = 4*8+4 = 36
