Answer:
AC ≈ 6.8 cm
Step-by-step explanation:
For legs a and b of a right triangle with hypotenuse c, the Pythagorean theorem tells us ...
a = √(c² -b²)
Using this relation, we can find legs CE and AE.
CE = √(3² -2²) = √5
AE = √(5² -2²) = √21
AC is the sum of these two lengths:
AC = AE +EC = √21 +√5
AC ≈ 6.8 cm
