Joel is constructing a line perpendicular toBW←→. He has already constructed three arcs as shown. He moves his compass point to W to construct a fourth arc. What must be true about the width of Joel’s compass opening before he draws the arc?

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β
