Answer:

  1.  7.1 cm

  2.  10.9 cm

Step-by-step explanation:

1. You know the legs of a right triangle must be shorter than the hypotenuse. The only answer choice shorter than 8 cm is 7.1 cm.

__

2. By the Law of Sines, ...

  AB/AC = sin(ACB)/sin(B)

  AB = AC·sin(72°)/sin(38°) = 1.545·AC

The approximate value of AC from problem 1 is sufficient to get you close to the answer.

  AB ≈ 7.1×1.545 ≈ 10.9 . . . cm
