Answer:
4
Step-by-step explanation:
In triangle ΔPQR, we have;
The incenter of the triangle = The point T = The point of the intersection of the angle bisectors
Therefore, the perpendicular distances from T to the sides of ΔPQR are the radius, r, of the inscribed circle of ΔPQR
∴ WT = UT = ST = r
From the figure, WT = 4
∴ WT = UT = ST = 4
ST = 4
