This is the diagram
Answer:
b=9
Step-by-step explanation:
This photo is the diagram now for the solution
using the Pythagoras theorem
we know that
C²=a²+b²
now we are looking for the third side we are given the value of A which is 6 and C which is 3√13 then that suppose that we are looking for b
we then make b the subject of the formula
C²=A²+B²
B²=C²-A²
B=√C²-√A²
then we substitute for the values
B=√(3√13)²-√6²
B=√117-√36
B=√81
B=9
