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 = ?, b = 13, c = 21


15.83
15.87
16.19
16.49

Answer 1

quadratics to triangles in one step
must be an on line class....

Answer 2

16.49?

Answer 3

\[a^2+b^2=c^2\] is the conclusion of pythagoras the one theorem everyone knows
so
\[a^2+13^2=21^2\] you gotta solve for \(a\)

Answer 4

You have to use the Pythagorean theorem

Answer 5

yeah you got it

Answer 6
