Question

Say that a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse. Find c if a = 15 and b = 20.                                                                            
A) c = 13                                                                  
B) c = 25                                                                    
C) c = 35                                                                   
D) c = 625

anonymous · Answer

$$
c=\sqrt{ a^2+b^2}= \sqrt{625}=25
$$
