In circle v, angle wxz measures 30°. line segments wv, xv, zv, and yv are radii of circle v. what is the measure of in circle v?

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex
