which statements are true regarding triangle lmn? check all that apply.

a. nm = x

b. nm = x squared 2

c. lm = x squared 2

d. tan(45) = squared 2 / 2

e. tan(45) = 1

Alright

for a 45-45-90 triangle, if the legs are x then the hytponuse is x√2

so LM=x√2 is right
NM=x

also, tan=oposite side/adjacent side
so that would be LN/MN or MN/LN=x/x=1

so that would be tan(45)=1

so you want to check the 1st one, 3rd one and 5th one

NM=x
LM=x√2
tan(45°)=1 are the answers
