What's the answer for this?

6.4 miles

Step-by-step explanation:

Use pythogoras theorem here:

? ²= 5² + 4² =

?² = 25 + 16=

?²= 41

?= √41

? = 6.4

You don't need to thank me, I hope this helped

Let d represent the distance from home to school

To find d we use the formula for Pythagoras theorem

That's

a² = b² + c²

Where a is the hypotenuse or the longest side

From the question

d is the hypotenuse

So we have

d² = 4² + 5²

d² = 16 + 25

d² = 41

Hope this helps you

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
