A round plate 
in. in diameter is to have ten holes drilled through it. This is accomplished by creating a drawing for half the circle and the then "mirroring" the drawing for the other half of the circle. The 
in. diameter holes are to be equally spaced on a 
style="vertical-align:-1px;" varid="variable_id_field" variablename="impvar_9d60b06a63a046538f1fc4609" class="wirisformula" /> in. concentric circle in the top half of the plate. What is the angle A between the holes? What is the angle B between the horizontal and each of the end holes?
