Start with the large equilateral triangles - they are easy to construct with straight-edge and compass. Then you can draw the larger circle easily enough - you don't need to use a 20° angle. The four smallest equilateral triangles are also easy to construct (I'm assuming the four intermediate equilateral triangles created by the intersection of the two large triangles are themselves equal in size to four of the smallest triangles.
