If y = 2.5 cm and z = 6.5 cm, what is the length of x?
a. 8 cm
b. 3 cm
c. 6 cm
d. 5 cm

The Pythagorean Theorem states that a^2 + b^2 = c^2.

In this case, 'a' would be 'x' and 'b' would be 'y', leaving 'c' to be 'z'.

x^2 + y^2 = z^2

x^2 + (2.5)^2 = (6.5)^2

x^2 + 6.25 = 42.25

Subtract 6.25 from both sides

x^2 = 36

Take the square root of both sides

x = 6 cm

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range
