Would be nice if you could just help me to at least start drawing (what to do first) the right way. Thanks.

1) Regular triangle:

b - a = 3cm

c = 6cm

γ = 120°

2) Regular triangle:

a + b + c = 16cm

\alpha = 75°

β = 60°

3) Isosceles triangle:

a + h = 8cm

γ = 30° (I found out that on hand of that we know that \alpha = β = 75°)
