Question

Ip : ABC-Triunghi
m(<) A) = 90 grade
AD=h
AM = mediana
AM=12
M(<)DAM) =30 grade
C: M(<)B) ; m(<)C) ; Aria si perimetrul ,

Answer 1

in tr dreptunghic mediana este jumatate din ipotenuza , deci BC=24. dacaUNGH DAM =30 GRADE, ATUNCI UNGH ABC=60GRADE, DECI UNGH  ACB=30 GRADE. Potrivit teoremei ungh 30 grade AB=BC/2=12. Conf th pitagora AC=12RADICAL3. P=36+12radical3=12(3+radical3), A=cxc/2=12X12radical3/2, A=72radical3
