Step-by-step explanation:
but if you really want to know most people have different ways of telling people how they got to their answer
For the first part, a is the answer because we want km over mi and for the second part, multiply 1km/0.62mi times 23km which equals 14.26 miles

An isosceles right triangle is a right triangle with two legs equal in length and has angles of

.
By Pythagorean Theorem, we know that,
hypotenuse
c

⇒
c
=
a
√

where
c
is the hypotenuse and
a
is the leg.
So for an isosceles right triangle with side length
a
, the hypotenuse has a length of
a
√

.
Similarly, if the hypotenuse of an isosceles right triangle has length of
a
, the legs have a length of
a

or

Given that the hypotenuse of the isosceles right triangle
