A hexagon has six sides, and an octagon has eight. 3 hexagons and 3 octagons have 3*6 + 3*8 sides = 18 + 24 sides = 42 sides altogether.
A decagon has 10 sides and an octagon has 8. 5*8 + 5*10 = 90 sides
Octagons have 8 sides and 8 vertices, the number of angles could be eight or if you are being pedantic the answer is 16 as each vertex has an internal and an external angle
24 sides
