Answer:
SV = 41 units
QT = 21 units
Explanation:
Please refer to the attached figure.
It is given that line segment TV has a perpendicular bisector as line N which intersects on line on TV at point R.
So, TR = RV
We are given that:

Comparing the values of TR and RV:

We can easily observe that due to the nature of the construction of this figure there is symmetry present.
As a result, we can draw the following conclusions:
1.

Putting value
:
2.

Putting value
:

Hence the values are:
SV = 41 units
QT = 21 units
