Give all possible names for each angle shown.calculation tip: in angle abc, b is the vertex.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

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
