Perimeter of a parallelogram is 72 meters. The width is 8 meters less than the height. Find the width and height of the parallelogram

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

In the triangles, bc =de and ac fe.if the mzc is greater than the mze, then ab isdfelth

This is about circle theorems. someone asap : (
