Question

If x represents the hypotenuse of this right triangle, which equation can be used to find the value of x?

Answer 1

For a right triangle with legs legnth a and b and hyptonuse c
a²+b²=c²

ok, so side lengths (legs) re 5 and 6, find c or x (c=x=hypotonuse)

6²+5²=x²
36+25=x²
61=x²
sqrt both sides
√61=x

well, the equation would be a²+b²=c² or
$\sqrt{a^2+b^2} =c$
