Answer:
Option C is correct
the value of b approximately is, 57 units
Step-by-step explanation:
Using Pythagoras theorem in a right angle triangle:
\(\text{Hypotenuse side}^2=\text{Opposite side}^2+\text{Adjacent side}^2\)
As per the statement:
In ACB,
a = 40 units , c = 41
Solve for b:
Using Pythagoras theorem;
\(b^2=a^2+c^2\)
Substitute the given values we have;
\(b^2 = 40^2+41^2\)
⇒\(b^2 = 3281\)
⇒\(b = \sqrt{3281} = 57.280014\) units
Therefore, the value of b approximately is, 57 units
