Measure the Angles of △ABC. Then measure the angles of △A' B' C' when △A' B' C' coincides with the other three triangles. Record the measure of each angle in the table.

Find the volume of the described solid.the solid lies between planes perpendicular to the x-axis at x = 0 and x=7. the cross sectionsperpendicular to the x-axis between these planes are squares whose bases run from the parabolay=-31x to the parabola y = 30/x.a) 441b) 147c) 864d) 882

Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?
