From the angle bisector theorem
we can first assume the third side is x, therefore
7.4/6 = x/4
x = 7.4 × 4/6
x = 4.93 cm
We can also use,
7.4/4 = x/6
x = 7.4 ×6/4
x = 11.1 cm
Therefore, the shortest length of the third side is 4.93 cm while the longest length is 11. 1 cm
and
so

and you rationalize denominator by multiplying numerator and denominatr by
so that gives--

Your answer is 
3.14
This is typically what you would use but there are several other numbers after 3.14
4 sorry I don’t know how to explain it. :(
Answer:
2 * 2 * 113
Step-by-step explanation:
452: 2 * 226
226: 2 * 113
113 is a prime number
452: 2 * 2 * 113
452: 2^2 * 113
