Given: ab=bc
the longest segment shown

a. ab
b. ad
c. dc

Answer

C. DC

Explanation

AB = BC.

From the diagram, <DAB = <DBC = 60°

<ADB = 180 - (60 + 60)

          = 180 - 120

            = 60°

But we have been given angle BDC = 37.5°.

Since the angle BDC is smaller than ADN, the line AD is smaller than DC. AB = AD since triangle ABD is an equilateral triangle.

∴ The longest segment shown is DC.
