Find the third side of the triangle. Round answer to one decimal place. 
A)a = 555.5 
B)a = 112.0 
C)a = 518.3

Quizplus · Accepted Answer

Using the Pythagorean theorem, we can solve for the missing side. 
a^2 + 42^2 = 540.5^2
a^2 = 540.5^2 - 42^2
a^2 = 294285
a = 518.3 (rounded to one decimal place)
