Answer:
PT=30 units
Explanation:
Given that:
Line PQ which has a mid point at T.
and

To find:
PT = ? in simplified terms.
Solution:
First of all, let us recall that mid point on a line segment is a point that divides the line in two equal parts.
In other words:
If a point B is the mid point of line segment AC, then AB = BC.
Here, the point T is the midpoint of PQ.
i.e. PT = TQ

Putting value of
in PT above:
