AC = 2 BD
Distance BD = √[(2.5+1)^2 +(3-3)^2]
Distance BD = √(3.5)^2
Distance BD = 3.5
AC = 2 * 3.5 = 7
Answer
d. 7
Wouldnt it be 4 im pretty sure i did the math right i hope this works can you answer mine?
180-140=40 (complementary angle)
2z=40
Z=40/2
Z=20

Answer:

Step-by-step explanation:
we know that
If the triangle of the figure is a regular polygon
then
Is an equilateral triangle
