Find the length of the third side of the right triangle. Give an exact answer and an approximation to three decimal places.
leg a = 27
hypotenuse = 30
leg b =
----------------------
b^2 = 30^2 - 27^2
b^2 = 900 - 729 = 171
b = sqrt(171)
b =~ 13.077

Use the Pythagorean theorem
a^2+b^2=c^2
27^2+b^2=30^2
729+b^2=900
Subtract 729 from both sides
b^2=171
take the square root of both sides
13.0766
13.077
