I would say this is false because Dan may be in another zero hour class.
C.
ABC = DEF
AB = DE , AC = DF & BC = EF ( means similar )
EF = 4times BC
So, the triangle DEF is 4times the triangle ABC
EF = 24 and BC = 6
So, AB = DE/4 = 32/4 = 8
We are given a figure with several given expressions:
EK = x + 5
KJ = x +5
FG = 2x
GH = 3x - 5
Assuming that the triangle is equilateral:
equate GH = FG
3x - 5 = 2x
solve for x
x = 5
therefore, one side of the triangle:
x + 5 + x + 5 = 20
and the perimeter of the equilateral triangle is
3*one side = 3 * 20 units
Thus, Perimeter = 60 units. <span />
