Three pictures are to be hung along a 12-foot wall. They should be evenly spaced from each other and from the ends of the wall. How far apart should the wall fasteners be placed?

leave a 1 ft space

so the fasterners should be placed 3 ft apart

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
