Answer:
The Pythagorean Theorem is a mathematical tool that is only applicable to right triangles. This mathematical concept indicates that in a right triangle the square of the hypotenuse is equal to the sum of the square of its legs:
c
2
=
a
2
+
b
2
. This theorem allows us to express one side of the triangle as a function of the other two known sides.

Answer:
the dryer costs $425
Step-by-step explanation:
x = washer
y = dryer
x + y = 803
x = y - 47
using the second equation a substitute in the first equation we get
y - 47 + y = 803
2y = 850
y = $425
FYI
x = y - 47 = 425 - 47 = $378
