30 + 54...GCF = 6
30/6 = 5
54/6 = 9
30 + 54 = 6 * 5 + 6 * 9 = 6(5 + 9)<==ur answer

Answer:
AC=18.1cm
Step-by-step explanation:
When we subtract 11-4=7cm we get one cathetus of the right triangle a=7cm also we know hypotenuse which is c=16cm.
We will use Pythagorean theorem to find the second cathetus b
b=√16∧2-7∧2= √256-49= √207 ≈ 14.39cm =DC =>
AC =√(DC)∧2+(AD)∧2= √14.39∧2+11∧2= √207+121= √328= 18.1cm
AC=18.1cm
