Question 310894
Two legs of a right triangle are the same.
 The hypotenuse is 6 meters, what is the length of the legs? What is the formula for this?
:
If both legs are that same you can use the formula:
a^2 + a^2 = c^2
2a^2 = 6^2
2a^2 = 36
Divide both sides by 2
a^2 = 18
a = {{{Sqrt(18)}}}
a = {{{sqrt(9*2)}}}
extract the perfect square
a = {{{3*sqrt(2)}}} length of the equal sides
or
a = 4.2464 if they want the decimal value
;
;
Check it on your calc: enter {{{sqrt(4.2464^2 + 4.2464^2)}}} result: 6.00
