Micah wants to insert a photo on his website. The current size of the photo is 1,800 pixels by 1,200 pixels. He wants to reduce the photo to 450 pixels by 300 pixels. What is the scale factor of the reduction?

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
