NemiM [27]

Answer:

the plans can go 560 miles per hour and in 10 hours it can travel 5600 miles

Step-by-step explanation:

1st divide miles over hour so you have to do 3360/6 and the solution you get for that equation is how far the plane can go in miles per hour 2nd for the second question you have to multiply your unit rate by the 10 hours so since our unit rate was 560 miles per hour you would multiply 360 and 10.

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
