Question

what is the value of b?
triangle efg with angle e, angle f, angle g marked equal (red arcs), side ef labeled 18, side fg labeled b. find b.
( b = square )

Explanation:

Step1: Identify triangle property

The triangle has all angles marked equal, so it is an equilateral triangle. In an equilateral triangle, all sides are equal.

Step2: Match equal sides

Side $EF = 18$, and side $FG = b$. Since all sides of an equilateral triangle are equal, $b = EF$.

Answer:

18
