Ok so the answer is 12/5 because twelve children sharing that means going into so that means fractions and fractions are really division. Good luck!
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
Answer:
x = -1
Step-by-step explanation:
<em><u>Add like terms (3 and 7, 2x and -10x and -x)</u></em>
x + 3 + 7 = 2x - 10x - x
x + 10 = -9x
<em><u>Subtract x from both sides:</u></em>
10 = -10x
<em><u>Divide both sides by -10:</u></em>
-1 = x
