Answer:
12/5
Step-by-step explanation:
Remember SOH CAH TOA
For this you will use a^2+b^2=c^2
So 21 would be your c^2 and 9 your b^2 so now it'll look like this
A^2+9^2=21^2
A^2+81=441
next you move the 81 over so you subtract 81 from both sides and you're left with
A^2=360
after you get the square root so a=18.9
and rounded you're answer would be B. 19 feet
