Question

Which is best estimate for the length of the short leg a if the hypotenuses c is about 10 cm 15 points!!

A)4 cm

B)5 cm

C)6 cm

D)8 cm

E)none of the above

Answer 1

whichever one was right hehehehe <3

Explanation:

Answer 2

A)4

Explanation:

Assuming all edges are integral values

The most basic right angles triangle with integral edges is

(3,4,5)

as it obeys pythogores theorem

which is

`a^(2)+ b^(2) =c^(2) \\\text{where c is the hypotenuse}\\\text{and a and b are the other side}`

`3^(2) +4^(2) =5^(2)`

Now, double each edge,it will still remain a right angled triangle since it will still obey pythogores theorem

so the edges are (4,6,10)

⇒4 cm is the short leg of a integral right triangle with hypotenuse 10 cm
