Question

Find the measure of RT. Assume the drawings are not drawn to scale.

Answer 1

4.5 cm

Explanation:

Given that segment RS = 2.0 cm, and segment ST = 2.5 cm, since point R, point S, and point T are collinear, therefore, based on segment addition postulate:

RS + ST = RT

2.0 cm + 2.5 cm = RT (Substitution)

4.5 cm = RT

RT = 4.5 cm.

Thus, the measure of segment RT given above is 4.5 cm.
