Question

The information given represents lengths of sides of a right triangle with c the hypotenuse. Find the correct missing length to the nearest hundredth. A calculator may be helpful.

a = 18, b = 26, c = ?

A.
31.16

B.
31.46

C.
31.62

D.
31.78

Answer 1

So if we have a right triangle with those sides



We can use the pythagorean theorem to solve for that hypotenuse...

\[\large A^2 + B^2 = C^2\]
Or more specifically
\[\large C = \sqrt{A^2 + B^2}\]

Just plug in your values to solve for 'c'

Answer 2

is it c?

Answer 3

for the people who'll need it, it is c
