Given polygon BRAIN~POWEQ what is the perimeter of BRAIN? A. 23.50 B. 58.75 C. 35.25 D. 57.25
what is your answer
please help someone ..
add BR, RI, IA, AN, NB
what do i do for the "y+5" though ? i can't add y ..
this is so confusing .. can you at least set it up in the formula how i should add it together ? i don't get it ....
I don't understand either.
add y+5+7.5+12.5+17.5++10
also add 4+14z+4.5+3+2x+1 for the other polygon compare them as they are same
but it only asks what the perimeter is for BRAIN . and what do i put in for y ? i can't just add y with the numbers .
Does the question provide any other information?
just the picture .
Maybe you have to make some sort of ratio if we assume they are similar shapes
equate 2x+1=12.5, 14z=7.5, 5+y=4.5, that should help you out
yes i thought of that but 10 does not = 4 nor does 7.5 = 3
think think,you are pretty close
add up all the sides. ANd use pythogorean theorom where necessary to get a side.
http://en.wikipedia.org/wiki/Pythagorean_theorem I still don't get it
Ell it seems (on first look) they did not supply enough numerical data...
please explain the pythagorean theorem
these are not right triangles so how does that apply?
can someone give me a formula ? i don't understand . ):
