Answer:

this question isn't quite clear, is the diagram of the triangle necessary for me to answer this question ?

Step-by-step explanation:

but by simple analysis,

since the "unknown" is b

option (a) which is 42 + b2 = 52 is the best equation.

because we are looking for the value of "b", therefore there should be letter "b" in equation we're going to use. hope you understand...

Hope this helps .
