Answer:
C. DE=52
Step-by-step explanation:
Because the triangle is equilateral (all sides being equal), the half of each side is equal to the sides of the smaller triangle. Since BC=26, DE would be double.
52
Applying Thales' Theorem
(DE) / (2AB) = 26 / (AB)
DE = (2AB)*26/ (AB)
DE = 2*26
DE = 52
It would be (0,0)
7-7=0 and 3.5-3.5=0
m > 15
