Answer:

The road running along the third side was 3 miles long.

Step-by-step explanation:

Given,

Length of hypotenuse = 5\ mi

Length of one leg = 4\ mi

We have to find the length of the third side.

Solution,

Since the field is in the shape of a right triangle.

So we use the Pythagoras theorem to find the length of the third side.

"In a right angled triangle the square of the hypotenuse is equal to the sum of the squares of other two sides".

On framing in equation form, we get;

c^2=a^2+b^2

Where 'a' = 1st side of right triangle

'b' = 2nd side of right triangle

'c' = hypotenuse

Now we put the given values and get;

5^2=4^2+b^2\\\\25=16+b^2\\\\b^2=25-16\\\\b^2=9

Now taking square root on both side, we get;

\sqrt{b^2} =\sqrt9\\\\b=3\ mi

Hence The road running along the third side was 3 miles long.

Answer in 5 min I GIVE U BRAINLIEST
telo118 [61]

This is the formula of finding the hypotenuse: a² + b² = c².

So the legs would be a and b.

4² + 4² = c²

c² = 16 + 16

c² = 32

c = √32  (Option C)
