Answer:

13.4

Step-by-step explanation:

since this is a right angled triangle go straight to using pythogras therom such that both of the shorter sides when each is squared is equal to the square of the longest side

so

a^2 + b^2 =c^2

4.6^2 +12.6^2=c^2

c^2=179.92

c=√179.92

c= 13.4

which c is the longer side BC is 13•4 to I do

Thanks
