Answer: H = 20
Step-by-step explanation:
To find the hypotenuse , we will use Pythagoras theorem, which states that
The square of the hypotenuse = the square of the adjacent + the square of the opposite.
Since , we are dealing with isosceles right triangle , this means that :
both the adjacent and the opposite are equal, using the formula to find the hypotenuse , let H represent the hypotenuse , then
=
+
= 400 + 400
= 800
Take the square root of both sides
H =
can be written as
x
Therefore :
H = x
H = 20x
H = 20
