The width and length of a rectangle (in feet)are consecutive odd integers. if the length is increased by 5 feet, the area of the resulting rectangle is 60 square feet. what is the area of the original rectangle?

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
