A right triangle is shown. One leg is labeled nine. The hypotenuse is labeled fifteen. The second leg is labeled with a question mark.

6

twelve

thirty-six

square root of three hundred six

Answer 1

twelve

Answer 2

Use Pythagoras theorem

Answer 3

Pythagorean therom=a^2+b^2=c^2
one leg is labeled, we can call it a, and hypotenuse is labeled, which is c.
apply them to formula, 9^2+b^2=15^2
81+b^2=225
isolate the variable, b^2=174
to get ride of square in b, you must square root both sides.
b=sqrt(174)
b=13.190905...etc or just leave it as b=sqrt(174)
