Question

Va rog sa ma ajutati !Urgent

Answer 1

l=7 cm (o consider latura bazei)
m=muchia laterala
AA' II BB'
tg 30⁰ =√3/3
BB'/B'C'=m/l=m/7=√3/3    ⇒ m=7√3/3 cm

l= o consider latura bazei
m=muchia laterala = 8
CC' II BB'
tg 45⁰ =1
l=m=8 cm

l=6 cm (o conside latura bazei)
m=muchia laterala
BB' II CC'
AC=6 cm
tg 60⁰ =√3
AC/C'C'=l/m=6/m=√3    ⇒ m=6/√3 =6√3/3=2√3 cm
