Answer:
60°
Step-by-step explanation:
Jenny drew a figure in art school and the figure is shown in the attached diagram.
The diagram is a regular hexagon and it has rotational symmetry.
Two of its sides is placed parallel to the x-axis.
Therefore, by rotating 60° the adjacent sides will become parallel to the x-axis and the figure remains the same and symmetric with respect to the coordinate axes. (Answer)
The answer is c.
Since a^2+b^2=c^2, b^2=c^2-a^2 thus,
16=4-b^2= srt. of 12
