Question

Given ∆QRS≅∆TUV, QS=5v+3, and TV=6v−9, find the length of QS and TV.?

a.
64°
b.
63°
c.
84°
d.
81°

Answer 1

If ∆QRS≅∆TUV, Their corresponding sides would be equal so, 
QS = TV
5v + 3 = 6v - 9
6v - 5v = 3 + 9
v = 12

Now, QS = TV = 5(12) + 3 = 60 + 3 = 63

In short, Your Answer would be Option B

Hope this helps!
