Question
The coordinates of the vertices of the triangle shown are A(1, 1), B(5, 1), and C(1, 5). Which measurement is closest to the length of CB in units?
Responses
A 4.7 units4.7 units
B 4.9 units4.9 units
C 5.7 units5.7 units
D 5.9 units
The length of CB can be found using the distance formula:
CB = √[(5-1)^2 + (1-5)^2]
CB = √[16 + 16]
CB = √32
CB ≈ 5.7 units
Therefore, the closest measurement to the length of CB is 5.7 units, which corresponds to option C.
