Answer:
178.29m
Step-by-step explanation:
solution: AC =250m
<BAC= 64 digre <ACB=43 digre
Solution: sum of all interior angel=180
64+43+<ACB= 180
<ACB=180-64-43=73 digre
from sine law
AB/sinC= AC/ sinB
AB=250x sin 43/sin 73
=178.29m

Answer:
Magcocomment sana ako kaso naalala ko sobrang dami ko nga palang gagawin. Maglilinis ng bahay, maghuhugas ng pinggan, magsisibak ng kahoy, maglalaba ng mga damit, mag o-online class, magpipinta sa bahay, bantayan ang aming store, magluluto ng ulam, at syempre magsasaing narin kaya wala na akong panahon para magcomment pa. Masyado na akong busy, na kahit magcomment di ko magawa. Masasayang lang ang ilang minuto ng buhay ko. Kaya sana maintindihan nyo ako dahil hindi madaling maging ako. Hirap na hirap na ako. Hays. Gusto ko talagang magcomment, kaso wag na lang siguro.
