Question

Using the Pythagorean theorem, find the hypotenuse (which is c) in cm:

a= 160 cm

b= 120 cm

c= ?

Answer 1

Use: \[a^2+b^2=c^2\] You know a and b...

Answer 2

Pythagoras theorem states that:

\[a^2+b^2=c^2\]

Does this help, or do you need further help?

Answer 3

yes. i do

Answer 4

go ahead @chaise

Answer 5

so.. c= 200 cm

or should c=200cm^2

Answer 6

a^2+b^2=c^2

Substituting in your values.

160^2+120^2=c^2
25600+14400=c^2
40,000=c^2

Taking the square root of both sides of the equal sign.

c=200cm

This is a length, and is only one dimensional, and thus has units of cm.

If it was an area, it would have units cm^2, if it was a volume it could have units cm^3.

You are right by saying 200cm.
