Question

The points P(3, -4), Q(9,-5), and R(5, -1)

are the vertices of a triangle. What is the
approximate length of side RQ? Round to
the hundredth.

Answer 1

5.66 units

Explanation:

R = (5,-1) Q = (9,-5)

CALCULATE DISTANCE:

9 to 5 is 4 units

-1 to -5 is 4 units

USE PYTHAGOREAN THEOREM:

4^2 + (4)^2 = 32

sqrt(32)= approximately 5.66 units
